Abstract: There is a significant gap between the textured surface with three successive reflections of new solar cell prototype with an anti-reflective layer and without an anti-reflective layer. This study concerns in particular the photovoltaic parameters such as the spectral response, the absorption coefficient and the generation rate. We have found that we are getting nearer to the ideal values in case we want to take advantage of ray incidence three times with an anti-reflective layer, then we will get good results. We have investigated with an anti-reflective layer and hence, making the penetrating rays rate to reach 90%, leading to the improvement of the spectral response, the absorption coefficient, the generation rate.
