Abstract
A high-quality solar cell is manufactured that prevents contamination of solar cell boundaries. A transparent conductive film, an amorphous silicon film, and a metallic electrode are continuously laminated onto a substrate, and etching is done of the transparent conductive film, the amorphous silicon film, and the metallic electrode, using a photoresist film having stepped thickness to achieve the desired shape. Insulation between solar cell elements is provided via a prescribed protective film, after which an electrically conducive paste is formed so as to make a series connection between solar cell elements.
