Why GaAs Is Used In Solar Cell

GaAs (gallium arsenide) is most ordinarily utilized in making of a solar cell (we call it GaAs Cell) because it absorbs relatively more energy from the incident solar radiations having relatively higher absorption co-efficient. Such properties are required for the fabrication of solar cells.

State the rationale , where GaAs is most ordinarily utilized in the assembly of asolar cell.

GaAs Solar Cell Used in Space Satellite

Hint: Full sort of GaAs is defined as Gallium Arsenide and it's used because the basis for our solar power .Gallium Arsenide may be a semiconductor material.This is an alloy which is formed as a mixture of both Gallium and Arsenide.This combination may be a very expensive material which is usually utilized in space technologies, this cell we can GaAs space solar cell.

The Advantage of GaAs Solar Cell

Gallium Arsenide can convert the solar power into electricity .There are numerous advantages for gallium arsenide. First one has a low-Temperature Coefficient.This material has an honest Low Light Performance.They are having a high efficiency also. the fabric is moisture resistant and excellentin radiating the UV rays. the fabric has been considered as flexible and light-weight also.Gallium arsenide is most generally utilized in the assembly of a photovoltaic cell because it can absorb relatively more energy from the incident solar radiations due to the relatively higher coefficient of absorption .This is thereason why the gallium arsenide has not been utilized in the assembly of a photovoltaic cell .

Gallium Arsenide GaAs VS Silicon

A number of the electronics characteristics of gallium arsenide are above that of silicon.Gallium arsenide has a better saturated electron velocity and greater mobility of electrons. this may allow the gallium arsenide transistors to function at frequencies above 250GHz.GaAs equipment are comparatively insensitive to overheating due to their higher energy band gap. they're creating less noise or disturbance within the electrical signal than silicon devices even at higher frequencies. This is because of the upper carrier mobility and lower resistive device characteristics. thanks to these properties,the gallium arsenide has been utilized in mobile phones, satellite communications also.
