Effects of diffuse spectral illumination on microcrystalline solar cells

The main objective of this work lies on the fundamental need of knowledge of the effect of variations in diffuse spectral distribution due to the variation of atmospheric parameters on the performance of a micro crystalline solar cell using the spectral irradiance model for clear skies SMARTS2 (Simple Model of the Atmospheric Radiative Transfer of Sunshine) on the site of Tlemcen. The results show that the efficiency is a function of atmospheric conditions and is not constant. it increases with increasing turbidity, water vapour content and albedo but it decreases with increasing air mass. The short circuit current increases with increasing turbidity and albedo, and it decreases with increasing air mass and atmospheric water vapor content for diffuse solar irradiance
