| Abstract: |
| Objective To improve the application efficiency of GaAs solar cell. Methods Grey-cables that were commonly used for spacecrafts were taken as the outgassing source, the effects of outgassing of non-metal materials on GaAs solar cell were analyzed through the relationship test between the power of solar cell and transmittance and the relationship test between the depositing mass of contaminants and transmittance. Results The short circuit current of GaAs solar cells decreased with the increase of deposition of outgassing of non-metal materials. The short circuit current of GaAs solar cells decreased by 23 mA and the variety ratio was 10.9% , when the depositing contaminants arrived at 4 × 10-5 g/cm2. The short circuit current of GaAs solar cells decreased by 42 mA and the variety ratio was 20.0%, when the depositing contaminants arrived at 6×10-4 g/cm2. Conclusion Outgassing of non-metal materials was one of the factors causing degenerated performance of solar cells. |
