Rating: Overweight (Maintained)
Executive Summary
The commercial aerospace industry is transitioning from an era of exploration to one of rapid commercialization and规模化 (scale-up), driven by strategic imperatives and emerging technological paradigms such as "Space Computing." This report posits that the proliferation of Low Earth Orbit (LEO) satellite constellations, coupled with the increasing power demands of onboard payloads, will fundamentally reshape the space photovoltaic (PV) market.
Our core investment thesis rests on three pillars:
1. Demand Surge: The convergence of satellite internet infrastructure deployment and the nascent space computing sector is driving an exponential increase in both the number of satellites launched and the power requirement per satellite. We project annual satellite launches to grow from 8,000 in the short term (2026-2030) to 500,000 in the long term (2035-2040).
2. Technological Iteration: The industry is undergoing a critical shift from rigid, high-cost Gallium Arsenide (GaAs) solutions toward lightweight, flexible alternatives. While GaAs remains dominant due to reliability, p-type Heterojunction (p-HJT) silicon technology is emerging as a viable mid-term solution due to its cost advantages and compatibility with mature terrestrial supply chains. Long-term, Perovskite/Silicon Tandem cells offer the highest efficiency potential but face stability hurdles.
3. Market Expansion: We estimate the total addressable market for space PV cells to expand from RMB 20.3 billion annually in the short term to RMB 314.7 billion in the long term. When accounting for the potential 100GW incremental demand from space data centers, the long-term market upside could exceed RMB 1 trillion.
We maintain an Overweight rating on the sector. Key beneficiaries include equipment leaders like Maxwell Technologies (Maiwei Shares) for their HJT/Tandem production lines, and module/cell innovators such as Risen Energy and Junda Shares, who are actively pivoting toward space-grade PV technologies. Investors should monitor risks related to launch cadence, technical validation timelines, and international regulatory competition.
Key Takeaways
1. The Strategic Imperative: From Connectivity to Compute
The global race for orbital resources has intensified. Under the International Telecommunication Union’s (ITU) "first-come, first-served" rule for frequency and orbit allocation, major economies are accelerating satellite deployments.
* US Leadership: SpaceX’s Starlink constellation currently has ~9,400 satellites in orbit, with a target of 42,000+ for communication and potentially millions for orbital data centers.
* China’s Response: China has initiated the "Guowang" (13,000 satellites) and "Qianfan" (14,000+ satellites) constellations. In December 2025, China applied for frequency/orbit resources for over 200,000 satellites, signaling aggressive expansion plans.
* New Driver – Space Computing: The bottleneck of ground-based data centers (energy consumption, heat dissipation, latency) is pushing compute infrastructure into space. "Space Computing" leverages the vacuum of space for efficient heat radiation and abundant solar energy for power. Major tech firms, including SpaceX (acquiring xAI), Google (Project Suncatcher), and Chinese entities like Zhijiang Laboratory, are deploying AI chips (H100, TPU) to orbit. This transforms satellites from simple relay nodes into high-power edge computing platforms, drastically increasing single-satellite power requirements.
2. Space Photovoltaics: The Sole Energy Solution
In the space environment, solar photovoltaics remain the only sustainable, engineering-viable energy source for satellites.
* Superior Irradiance: Space solar irradiance is approximately 1,360 W/m², significantly higher than terrestrial averages, with near-continuous exposure in LEO.
* Power System Architecture: The standard power system comprises solar arrays (primary source), lithium-ion battery packs (storage for eclipse periods), and power control units. Solar arrays represent a significant portion of the satellite’s cost and mass.
* Dual Growth Drivers:
1. Volume: The sheer number of satellites required for global coverage.
2. Intensity: The shift from basic communication to high-throughput laser links and onboard AI processing requires single-satellite power to rise from ~6kW (short term) to ~60kW (long term).
3. Technological Evolution: The Shift to Flexible & Lightweight
As launch costs decrease but payload constraints remain, the mass-to-power ratio (W/kg) and volume-to-power ratio (W/m³) of solar arrays have become critical performance metrics. This drives the transition from rigid to flexible structures.
| Feature | Rigid Solar Arrays | Semi-Rigid Solar Arrays | Flexible Solar Arrays |
|---|---|---|---|
| Core Structure | Aluminum Honeycomb | High-strength Frame + Fiber Mesh | Composite Thin Film |
| Substrate Thickness | Thick (20-30mm) | Moderate | Ultra-thin |
| Mass-to-Power Ratio | ~70-100 W/kg | ~75-120 W/kg | Up to 175 W/kg |
| Volume-to-Power Ratio | ~4 kW/m³ | ~4 kW/m³ | Up to 33 kW/m³ |
| Stowage Efficiency | Low (requires gaps) | Moderate | High (tight folding) |
| Maturity/Reliability | Very High | High | Moderate (Improving) |
| Primary Advantage | Proven Reliability | Better Heat Dissipation | Lightweight & Compact |
- Current Dominant Tech: Multi-Junction Gallium Arsenide (GaAs).
- Pros: High efficiency (>30%), excellent radiation resistance, low degradation.
- Cons: Extremely high cost due to scarce materials (Ge, Ga) and complex MOCVD manufacturing processes. Low yield in substrate stripping/reuse techniques.
- Emerging Mid-Term Tech: p-type Heterojunction (p-HJT) Silicon.
- Why HJT? Leverages mature terrestrial晶硅 (crystalline silicon) supply chains for significant cost reduction. HJT’s symmetric structure allows for better stress distribution in flexible applications.
- Why p-type? In space, p-type silicon demonstrates superior radiation hardness compared to n-type. High-energy particles create defects that act as recombination centers; these defects capture electrons less aggressively in p-type material, preserving minority carrier lifetime.
- Status: Maxwell Technologies achieved a record 26.92% efficiency for full-area HJT cells in Jan 2026.
- Long-Term Frontier: Perovskite/Silicon Tandem.
- Pros: Theoretical efficiency limits up to 43%. Perovskite has a high absorption coefficient ($10^5 cm^{-1}$), allowing for ultra-thin, lightweight layers. Significant cost-down potential as efficiency scales.
- Cons: Stability issues under UV radiation and thermal cycling. UV photons (3.1-4.43 eV) exceed the bandgap (1.5-2.3 eV), causing lattice defects and chemical bond breaking. Encapsulation and material engineering are key R&D focuses.
- Progress: Risen Energy achieved 30.99% efficiency in Perovskite/HJT tandem cells (Dec 2025). Junda Shares broke 33.53% in small-area Perovskite/TOPCon tandems (Jan 2026).
4. Market Sizing: A Trillion-Yuan Opportunity
We model the space PV market across three phases, factoring in satellite volume, single-satellite power, and technology penetration rates.
Table 1: Space Photovoltaic Market Size Forecast
| Metric | Short Term (2026-2030) | Mid Term (2030-2035) | Long Term (2035-2040) |

| Global Satellite Launches (10k/yr) | 0.8 | 3.0 | 50.0 |
| - China (10k/yr) | 0.25 | 1.3 | 25.0 |
| - US (10k/yr) | 0.5 | 1.3 | 20.0 |
| Avg. Single Satellite Power (kW) | 6 | 20 | 60 |
| Total Annual Power Demand (GW) | 0.05 | 0.60 | 30.0 |
| Tech Penetration: GaAs | 81% | 20% | 1% |
| Tech Penetration: p-HJT | 13% | 60% | 45% |
| Tech Penetration: Perovskite Tandem | 6% | 20% | 54% |
| GaAs Market Value (RMB Bn/yr) | 19.5 | 60.0 | 150.0 |
| HJT Market Value (RMB Bn/yr) | 0.5 | 14.4 | 67.5 |
| Perovskite Market Value (RMB Bn/yr) | 0.3 | 6.0 | 97.2 |
| Total Base Market (RMB Bn/yr) | 20.3 | 80.4 | 314.7 |
Note: Costs assumed to decline significantly for HJT and Perovskite due to scale and efficiency gains. GaAs costs remain high.
Upside Scenario: Space Computing Data Centers
If space computing matures as projected by Musk and other tech giants, adding 100GW of incremental power demand for orbital data centers (at an estimated unit cost of RMB 12.6/W), this could add an additional RMB 1.049 trillion to the long-term market size. This underscores the asymmetric upside potential of the sector.
Risks / Headwinds
While the structural growth trajectory is compelling, investors must navigate several key risks:
- Launch Cadence & Cost Reduction Delays: The economic viability of large constellations depends on frequent, low-cost launches. Any stagnation in the development of reusable rockets (e.g., delays in SpaceX Starship or Chinese commercial rocket equivalents) could slow deployment rates and compress margins for satellite manufacturers.
- Technology Iteration & Industrialization Risks:
- Stability of Perovskites: If the stability issues of perovskite cells under harsh space conditions (UV, thermal cycling, atomic oxygen) cannot be resolved within the expected timeframe, the long-term cost-down thesis may fail, keeping the market reliant on expensive GaAs.
- HJT Adoption: The transition from n-type to p-type HJT for space applications requires rigorous validation. Failure to demonstrate superior radiation hardness in orbit could hinder adoption.
- International Regulatory & Standard Competition: The "first-come, first-served" nature of ITU rules creates geopolitical friction. Potential trade barriers, export controls on dual-use technologies (chips, advanced materials), or conflicting international standards for space debris and spectrum usage could disrupt supply chains and market access.
- Uncertainty in Space Computing Demand: The business case for orbital data centers is still theoretical. Challenges in high-bandwidth laser inter-satellite links, data downlink bottlenecks, and the actual computational advantage over next-gen ground centers remain unproven at scale. If the "Space Compute" narrative fails to materialize, the high-end power demand projections (60kW/satellite) may be overstated.
Rating / Sector Outlook
Sector Rating: Overweight (Maintained)
We believe the commercial aerospace sector is entering a pivotal inflection point. The convergence of national strategic mandates (satellite internet sovereignty) and commercial innovation (SpaceX’s vertical integration, space computing) creates a durable multi-year growth cycle.
The space photovoltaic sub-sector, in particular, offers a unique value proposition: it is a critical bottleneck component with high technical barriers and a clear path to cost reduction through terrestrial technology spillovers (HJT/Perovskite). Unlike satellite manufacturing, which is fragmented, the PV cell market benefits from the massive scale of the global terrestrial solar industry, allowing for faster learning curves and cost declines.
We expect the sector to outperform the broader market as earnings visibility improves with the commencement of large-scale constellation deployments (Guowang/Qianfan) in 2026-2027.
Investment View
We recommend focusing on companies with technological leadership in high-efficiency, lightweight PV cells and those with strategic partnerships in the space supply chain.

Final Thoughts for Institutional Investors
The commercial aerospace sector, specifically space photovoltaics, represents a classic "Growth at a Reasonable Price" (GARP) opportunity if viewed through the lens of long-term technological substitution. While current financials of solar companies are pressured by terrestrial oversupply, the space segment offers a high-margin, low-volume niche that is immune to terrestrial price wars and is poised for exponential growth.
Strategy:
1. Accumulate on Weakness: Use any short-term volatility in the broader solar sector to build positions in these specialized players.
2. Monitor Technical Validation: Closely track the on-orbit performance data of p-HJT and Perovskite prototypes launched in 2026-2027. Successful validation will be the trigger for re-rating.
3. Diversify Across the Value Chain: Hold a mix of equipment providers (Maxwell) for early-cycle gains and cell/module integrators (Risen, Junda) for later-cycle volume growth.
The "Starlink Effect" has proven the viability of large-scale LEO constellations. The next wave, driven by China’s strategic response and the advent of Space Computing, will require a new generation of power systems. The companies identified above are best positioned to capture this value transfer from traditional GaAs suppliers to next-gen silicon-based innovators.
Appendix: Detailed Industry Analysis & Data Support
(Note: The following sections provide deeper context and data visualization descriptions referenced in the main report, ensuring comprehensive coverage for institutional due diligence.)
A. Commercial Aerospace Landscape: The US-China Duopoly
The global commercial launch market is effectively a duopoly between the United States and China, with other nations playing niche roles.
1. Launch Frequency & Capacity
* United States: Dominated by SpaceX. In 2025, SpaceX conducted 167 successful launches, a 24% YoY increase. The Falcon 9 remains the workhorse, while the Starship program is ramping up for heavy-lift and fully reusable operations. This high frequency is the backbone of the Starlink deployment strategy.
* China: In 2025, China conducted 92 launches, a 35% YoY increase. Notably, commercial launches accounted for over 50% of the total, indicating a vibrant private sector emergence (e.g., LandSpace, Galactic Energy, iSpace). The government’s support for the "Guowang" and "Qianfan" constellations is driving this surge.
2. Satellite Types & Orbits
* LEO (<2,000 km): The primary focus for commercial aerospace due to low latency (20-50ms) and lower launch energy requirements. Ideal for broadband internet (Starlink, Kuiper) and real-time remote sensing.
* MEO (2,000-36,000 km): Primarily used for navigation (GPS, Galileo, BeiDou). Less relevant for the current commercial boom.
* GEO (>36,000 km): Traditional communication and weather satellites. High latency makes them unsuitable for modern interactive applications, leading to a gradual shift of commercial investment away from GEO towards LEO.
3. Application Scenarios Driving Demand
* Satellite Internet: Bridging the digital divide in remote areas (oceans, deserts, mountains).
* Autonomous Driving & Low-Altitude Economy: Robotaxis (e.g., CaoCao Chuxing’s Robotaxi 2.0) and drones require continuous, high-precision positioning and communication, which terrestrial networks cannot provide globally. LEO satellites offer seamless coverage.
* Remote Sensing: Real-time monitoring of agriculture, disaster response, and military surveillance. The integration of AI on-board (Space Computing) allows for immediate analysis, reducing the need to downlink raw data.
B. The Space Computing Paradigm Shift
The concept of "Space Computing" is not merely speculative; it is a response to physical limitations on Earth.
1. The Energy Bottleneck on Earth
Ground-based AI data centers are consuming unprecedented amounts of electricity. Training large language models (LLMs) and running inference for billions of users strains national grids.
* Space Advantage: Solar irradiance in space is constant and intense. A satellite in LEO experiences ~15 orbits per day, with roughly 60% of that time in sunlight. With high-efficiency solar arrays, power generation is predictable and abundant.
2. The Thermal Bottleneck on Earth
High-performance chips (like NVIDIA H100/B100) generate immense heat. Cooling these chips requires massive amounts of water and electricity for HVAC systems.
* Space Advantage: The background temperature of deep space is ~3K (-270°C). Heat can be dissipated via radiation without the need for convective cooling (fans/water). This allows for higher chip density and potentially higher sustained clock speeds.
3. The Latency & Bandwidth Bottleneck
For Earth observation, sending terabytes of raw imagery to ground stations is slow and bandwidth-constrained. Only <10% of collected data is typically downlinked due to these constraints.
* Space Advantage: "Compute at the Edge" (in orbit). By processing data on the satellite, only actionable insights (e.g., "ship detected at coordinates X,Y") are sent down. This reduces bandwidth requirements by orders of magnitude and enables real-time decision-making for defense and logistics.
4. Key Players & Timelines
* SpaceX/xAI: The acquisition of xAI by SpaceX in Feb 2026 is a strategic masterstroke. It vertically integrates the hardware (Starship/Starlink), the power (Solar), and the intelligence (xAI models). The goal of 100GW of orbital data center capacity implies a massive demand for power generation systems.
* Google (Project Suncatcher): Launching TPU-equipped prototypes in 2027 signals that Big Tech is seriously evaluating space as a compute tier.
* China (Zhijiang Lab): The "Three-Body Computing Constellation" aims for 100 satellites by 2027. This state-backed initiative ensures that China will not fall behind in the space compute race.
C. Technical Deep Dive: Why p-HJT for Space?
The choice of p-type Heterojunction (p-HJT) over n-type HJT for space applications is a nuanced technical decision driven by radiation physics.
1. Radiation Damage Mechanism
Space is filled with high-energy protons and electrons (Van Allen belts, solar flares). When these particles strike a silicon lattice, they displace atoms, creating defects. These defects act as recombination centers, trapping charge carriers (electrons and holes) and preventing them from contributing to current. This leads to a drop in efficiency (degradation).
2. Minority Carrier Lifetime
* n-type Silicon: The majority carriers are electrons. The minority carriers are holes. Defects in n-type silicon tend to trap holes very effectively, drastically reducing the minority carrier lifetime. Since current generation depends on the collection of minority carriers, n-type cells degrade faster.
* p-type Silicon: The majority carriers are holes. The minority carriers are electrons. Defects in p-type silicon have a lower capture cross-section for electrons. Therefore, the minority carrier lifetime is preserved better under radiation.
3. HJT Structure Benefits
* Symmetry: HJT cells have a symmetric structure (transparent conductive oxide layers on both sides). This allows for balanced mechanical stress when the cell is bent or folded into flexible arrays.
* Low Temperature Coefficient: HJT performs better at high temperatures. While space is cold, localized heating from solar concentration or electronics can occur. HJT’s stability ensures consistent output.
* No LID (Light Induced Degradation): Unlike PERC cells, HJT does not suffer from LID, ensuring stable performance from day one.
4. Manufacturing Synergy
The terrestrial solar industry is heavily invested in HJT. By adapting p-HJT for space, companies can leverage existing gigawatt-scale supply chains for wafers, pastes, and equipment, achieving economies of scale that GaAs manufacturers cannot match.
D. Perovskite Tandem: The Holy Grail and Its Challenges
Perovskite/Silicon tandem cells represent the theoretical peak of PV technology for space, but they are not yet ready for prime time.
1. Efficiency Potential
* Single Junction Limit: Silicon cells are limited to ~29% efficiency (Shockley-Queisser limit). GaAs is ~33%.
* Tandem Advantage: By stacking a Perovskite layer (absorbing blue/green light) on top of a Silicon layer (absorbing red/infrared light), the cell utilizes the solar spectrum more completely. Theoretical limits exceed 40%.
2. Stability Issues
* UV Instability: Perovskite materials degrade under UV light. The high-energy photons break chemical bonds in the perovskite lattice.
* Thermal Cycling: Satellites experience extreme temperature swings (from -150°C in shadow to +120°C in sunlight) every 90 minutes in LEO. This causes mechanical stress and delamination in multi-layer structures.
* Ion Migration: Ions within the perovskite lattice can migrate under electric fields and heat, leading to hysteresis and permanent degradation.
3. Mitigation Strategies
* Encapsulation: Advanced barrier films (e.g., CPI - Colorless Polyimide) are being developed to block moisture and oxygen while remaining flexible and transparent.
* Interface Engineering: Modifying the interface between the Perovskite and Silicon layers to prevent ion migration and improve mechanical adhesion.
* Composition Tuning: Adjusting the chemical composition of the perovskite (e.g., mixing cations and anions) to enhance intrinsic stability.
4. Investment Implication
Investors should view Perovskite as a long-term option. Companies like Junda and Risen are making progress, but widespread adoption in space likely awaits further validation missions in the 2028-2030 timeframe. In the interim, p-HJT will capture the market share shifting away from GaAs.
E. Financial Modeling Assumptions
Our market size calculations are based on the following conservative assumptions:
-
Satellite Launch Volume:
- Short Term (2026-2030): Driven by initial phases of Guowang and Qianfan, plus continued Starlink V2/V3 deployment. Average 8,000 launches/year globally.
- Mid Term (2030-2035): Acceleration of Chinese constellations and start of space computing pilots. Average 30,000 launches/year.
- Long Term (2035-2040): Mature global coverage and large-scale space data centers. Average 500,000 launches/year (including smaller CubeSats and large compute nodes).
-
Single Satellite Power:
- Short Term: 6kW. Typical for current broadband communication satellites.
- Mid Term: 20kW. Increased payload complexity, laser inter-satellite links.
- Long Term: 60kW. High-power compute nodes and advanced radar/communication hybrids.
-
Technology Penetration:
- GaAs: Starts at 81% (current standard) but declines rapidly as costs become prohibitive for mega-constellations.
- p-HJT: Starts at 13% (early adopters) and grows to 60% in mid-term as reliability is proven and costs drop. Stabilizes at 45% long-term as Perovskite takes share.
- Perovskite Tandem: Starts at 6% (niche/experimental) and grows to 54% long-term as stability issues are resolved and efficiency advantages become undeniable.
-
Unit Cost (RMB/W):
- GaAs: Remains high at RMB 500/W due to material scarcity.
- HJT: Drops from RMB 80/W to RMB 5/W due to scale and efficiency gains.
- Perovskite: Drops from RMB 100/W to RMB 6/W, eventually undercutting HJT due to simpler processing.
F. Regulatory & Geopolitical Context
1. ITU & Spectrum Rights
The International Telecommunication Union (ITU) allocates orbital slots and frequency bands. The "first-come, first-served" rule incentivizes rapid deployment. Countries that file plans and launch "paper satellites" (placeholder launches) secure rights. China’s recent filing for 200,000 satellites is a defensive move to secure spectrum rights against US dominance. This creates a time-sensitive demand for satellite manufacturing and launch services.
2. Export Controls
The US has imposed strict export controls on advanced semiconductor chips and manufacturing equipment. This could impact the global supply chain for space computing chips. However, it also accelerates China’s domestic substitution efforts, benefiting local suppliers like Maxwell and Junda.
3. Space Debris & Sustainability
As constellations grow, space debris becomes a critical risk. Regulatory bodies may impose stricter end-of-life deorbiting requirements. This favors satellites with reliable propulsion and power systems (to maneuver out of orbit), further emphasizing the importance of high-reliability PV systems.
G. Company-Specific Risk Assessment
Maxwell Technologies:
* Strength: Monopoly-like position in high-end HJT equipment.
* Weakness: High valuation multiples; dependent on customer capex.
* Mitigation: Diversification into semiconductor packaging equipment.
Risen Energy:
* Strength: Strong brand in HJT modules; global sales network.
* Weakness: Balance sheet stress from terrestrial losses.
* Mitigation: Spin-off or separate financing for space division; cost leadership in HJT.
Junda Shares:
* Strength: Aggressive M&A strategy; vertical integration into satellite manufacturing.
* Weakness: Execution risk in integrating disparate businesses (cell mfg + satellite mfg).
* Mitigation: Retaining founding teams of acquired companies; phased integration.
Conclusion
The commercial aerospace industry is no longer a niche frontier but a central pillar of future global infrastructure. The convergence of connectivity and computation in space creates a robust, multi-decade growth runway. Space photovoltaics, as the enabling energy technology, stands to benefit disproportionately from this trend.
While GaAs has served the industry well, the economics of mega-constellations demand a shift to silicon-based and tandem technologies. p-HJT is the bridge technology that offers immediate cost relief and reliability, while Perovskite Tandem promises the ultimate efficiency ceiling.
For institutional investors, the key is to identify companies that are not just participating in this transition but leading it. Maxwell, Risen, and Junda represent distinct but complementary exposures to this theme. We recommend a strategic overweight position in the sector, with careful monitoring of technical milestones and launch cadences in the coming 12-24 months.
The stars are no longer the limit; they are the next market.
