Abstract

PURPOSE:To simplify a manufacturing process by forming an insulating film on the back of a substrate in thickness thicker than a circling-round of the surface of the substrate at an edge of the substrate before applying a diffusion source. CONSTITUTION:The semiconductor substrate 21 is chemically etched previously in order to remove a crushed layer due to slicing, etc., and the flatness of the edge section of the substrate is damaged. The insulating film 23 in SiO2, etc. is grown on the back according to a sputtering method, and circled round onto not only the back 22 and a side surface but the surface. The diffusion source is applied, and a doped oxide film 24 is formed. Accordingly, the circling-round is generated similarly at the edge section of the substrate, and the doped oxide film is made up on the SiO2 film. The solar cell is completed only by removing the doped oxide film used for diffusion and the insulating film without generating a short circuit even when the electrodes of both sides are formed. Thus, the complicated mesa-etching process is unnecessitated, and the process is largely simplified.
