Abstract

A crystalline solar cell is provided that includes a front-sided n-doped area and a rear-sided p-doped area, a front-sided contact, a rear-sided contact and at least one front-sided first layer made from SiN. In order to reduce degradation of the parallel resistance, a second layer made of at least one material selected from the group SiN, SiOx, Al2Ox, SiOxNy: Hz, a-Si:H, TiOx or containing said type of material is disposed between the first layer and the n-doped area and is then doped for forming imperfections.
