Question

why is GaAs used in making solar cell​

Answer 1

Solar cells and detectors. Gallium arsenide (GaAs) is an important semiconductor material for high-cost, high-efficiency solar cells and is used for single-crystalline thin film solar cells and for multi-junction solar cells.

Answer 2

Gallium Arsenide (GaAs) is a semiconductor material and a compound of Gallium and Arsenic . Advantages of Gallium Arsenide over Silicon :

1.Low Temperature Coefficient

2.Good Low Light Performance

3.High Efficiency

4.Excellent UV, Radiation and Moisture Resistance

5.Flexible and Lightweight
