The work referred to research on the factors which may contribute to decrease the efficiency of solar cells. Progressive degradation process for multi- and mono -crystalline solar cells was observed. Optical measurements showed that effective reflectance is worse for mc-Si than Cz-Si cells although they were coated antireflectol layer. It is caused generally by their heterogeneous structure. The process of texturization in case of Cz-Si improves their optical parameters. On the other hand it contributes to faster oxidation their surfaces. The process of obsolescence was finally corroborated by electrical measurements. The simulation of impact of heating showed, that its high values cause decrease of solar cells efficiency.
