Abstract
The work presented in this study is concerned the development of a new solar cell prototype in order to improve photovoltaic efficiency In this model we show that the material can have five and more successive incident ray absorptions instead of three currently, where we changed the direction of the reflected ray, by varying the angle between the two neighbouring pyramids, the incidence angle, the opening between the heads of the two closest pyramids and their height. Thus, with an angle between the two neighbouring pyramid varying between 24° and 12° and for angle of incidence varying between 78° and 84°. For these values of the angle between the two neighbouring pyramids and incidence angle, the opening between the heads of the two closest pyramids varied respectively from 4.25 to 2.10 μm for a pyramid height of 10 μm. This lead to a substantial increase of the spectral response and the photovoltaic efficiency.
