Abstract
In a photoelectric conversion device having numerous crystalline semiconductor grains deposited on a substrate, the substrate includes an aluminum layer or an aluminum alloy layer, an intermediate layer, and a base material layer, in which the intermediate layer is arranged such that it is composed mainly of one or a plurality of elements selected from among nickel, titanium, chromium, and cobalt. With the constitution as above, it is possible to suppress reaction between the aluminum electrode layer and the base material layer, thereby maintaining the high adhesiveness of the aluminum electrode layer. A photoelectric conversion device with high reliability and high conversion efficiency is therefore realized.
