Optical effects of the rectangular-like periodic textures introduced at the interfaces of a-Si:H solar cells on the short circuit current and external quantum efficiency were studied by 2-D simulations. Three main interdependent effects that occur due to the periodic-texture were analysed in the paper. These three effects are the antireflective effect, improved light scattering and the optical losses in back metal layer and they strongly influence the overall performance of the cell.
