Question

State the reason, where $GaAs$ is most commonly used in the production of a solar cell.

Answer 1

Full form of $GaAs$ is defined as Gallium Arsenide and it is used as the basis for our solar energy. Gallium Arsenide is a semiconductor material. This is an alloy which is made as a combination of both Gallium and Arsenide. This combination is a very expensive material which is mostly used in space technologies.

Complete step by step answer:
Gallium Arsenide can convert the solar energy into electrical energy. There are so many advantages for gallium arsenide. First one is having a low-Temperature Coefficient. This material is having a good Low Light Performance. They are having a high efficiency also. The material is moisture resistant and excellent in radiating the UV rays. The material has been considered as flexible and lightweight also. Gallium arsenide is most generally used in the production of a solar cell as it can absorb relatively more energy from the incident solar radiations because of the relatively higher absorption coefficient. This is the reason why the gallium arsenide has not been used in the production of a solar cell.

Note: Some of the electronics characteristics of gallium arsenide are higher than that of silicon. Gallium arsenide is having a higher saturated electron velocity and greater mobility of electrons. This will allow the gallium arsenide transistors to function at frequencies higher than $250GHz$. GaAs equipment are comparatively insensitive to overheating because of their higher energy band gap. They are creating less noise or disturbance in the electrical signal than silicon devices even at higher frequencies. This is because of the higher carrier mobility and lower resistive device characteristics. Due to these properties, the gallium arsenide has been used in mobile phones, satellite communications also.
