A photoelectric conversion device according to the present invention comprises an aluminum substrate or a substrate formed with an aluminum layer thereon, numerous p type crystalline semiconductor particles deposited on the substrate, an insulator interposed among the numerous p type crystalline semiconductor particles, and a n type semiconductor region formed on the upper portions of the p type crystalline semiconductor particles. An alloy portion comprising the aluminum and the semiconductor material is formed in a boundary part between the aluminum layer and the p type crystalline semiconductor particles, and a p+ region is formed in an interfacial part between the alloy portion and the p type crystalline semiconductor particle on the side of the p type crystalline semiconductor particle. Accordingly, reliability of the joining condition between the substrate and the crystalline semiconductor particles can be improved, thereby realizing a photoelectric conversion device having high conversion efficiency.
