Abstract: In this study, the development of a new solar cell prototype is presented in order to improve photovoltaic efficiency. In this model we show that the material can have three successive incident ray absorptions instead of two currently, by varying the incidence angle, the aperture between the summit of two neighboring pyramids and their height. This study concerns in particular the photovoltaic parameters such as the spectral response, the absorption coefficient and the generation rate. This model was checked for angles varying between 54 and 60° and for pyramid heights between 5 and 10 μm. For these values of incidence angle, the apertures between the summits of two neighboring pyramids varied respectively from 14.54 to 11.54 μm for a pyramid height of 10 μm.
