1U Satellite Board Standard GaAs Solar Panel

Product Details

Gallium arsenide (GaAs) belongs to the III-V group of compound semiconductor materials, and its energy gap is more suitable for matching with the solar spectrum, and it can withstand high temperatures. Compared with silicon solar cells, gallium arsenide solar cells have better performance.

The band gap of GaAs solar cells is wider than that of silicon, which makes its spectral responsivity and spatial solar spectral matching ability better than that of silicon. At present, the theoretical efficiency of silicon cells is about 23%, while the theoretical efficiency of single-junction gallium arsenide solar cells reaches 27%, and the theoretical efficiency of multi-junction gallium arsenide solar cells exceeds 50%. At present, China's mass production level can reach more than 30%.
