Abstract
A photovoltaic device is provided which can selectively and stably control the color of an intended exterior surface, particularly a light-incident surface side, of the photovoltaic device, and which exhibits high performance. A diffuser layer is provided on a light incident plane side of the photovoltaic device for scattering and dispersing incident light. By providing a coloring layer thereon to color incident light or using a structure where the diffuser layer itself is colored, reduction of photoelectromotive force performance is minimized while adding color to the photovoltaic device.
