P-type HJT powering lightweight, radiation-resistant space systems.

• Technical Highlights Overview

The p-type HJT space solar cell combines ultra-thin silicon wafer technology with a symmetrical heterojunction structure, achieving an optimal balance of efficiency, weight and reliability.

1. 26.65%/24.0% AM 1.5G/AM0 Maximum Efficiency (BOL)
2. <60μm Ultra-thin silicon wafer thickness
3. 19.2% AM0 Maximum Efficiency (End-of-Life)

• Battery Structure Comparison

P-type HJT cells employ a symmetrical heterojunction structure and low-temperature processing, combining high efficiency with ultra-thin, flexible characteristics; III-V multi-junction cells achieve the highest efficiency but carry extremely high costs.

• Ultra-thin and flexible, suitable for diverse spacecraft configurations

1. Customised Thickness
2. Bending performance

• Radiation resistance and technical validation

1. Strong resistance to displacement damage
2. Low carrier removal rate
3. Low radiation-induced defect concentration
4. Self-healing effect
