Abstract
A photovoltaic device has a semiconductor layer; electrodes and a surface protection layer adjacent to the light incident side. Granules of a material different from those of the surface protection layer are disposed in the surface protection layer. The granules in the surface protection layer have an average grain size of 0.001-20 microns, a surface density S from 0.2 to 0.9 and/or a density per volume from 0.001 to 0.5. To produce a surface protecting layer for a photovoltaic device in which the surface protecting layer has granules at a light incident side the surface of a photovoltaic device is painted with a liquid resin containing the granules.
