Design of GaAs solar cell front surface anti-reflection coating
2013
Based on a variety of dielectric film materials are of different refractive rate, design anti-reflection coating structure applying on the GaAs solar cell front surface in transfer matrix method (TMM), the optical absorption effect showed by different coating structure are analyzed and evaluated. Results show that: the three-layer anti-reflection film structure composed of three different dielectric film material has a smaller reflection loss than single-layer coating and double coating in GaAs cells absorb spectrum (300 nm ~ 867 nm wavelength range), for different incident angles, the reflectivity of incident light can be reduced to less than 5%.
