Abstract
This invention intends to develop a technique for forming an interlayer with excellent optical characteristics and to provide a photoelectric conversion device having high conversion efficiency. To realize this purpose, a series connection through an intermediate layer is formed in the thin-film photoelectric conversion device of the invention, and the interlayer is a transparent oxide layer in its front surface and n pairs of layers stacked therebehind (n is an integer of 1 or more), wherein each of the pair of layers is a carbon layer and a transparent oxide layer stacked in this order. Film thicknesses of each layer are optimized to improve wavelength selectivity and stress resistance while keeping the series resistance.
