Abstract
A photovoltaic device comprises a photoactive layer for generating carriers when light is applied thereto, and a window layer containing at least silicon and hydrogen and provided on the light incidence side of the photoactive layer. Hydrogen concentration in the window layer is higher in the layer's light incidence side than in the side facing the photoactive layer. Thus, the light incidence side of the window layer has a rough surface.
