Abstract

PURPOSE: To encircle the periphery of a solar battery constituted by PN junctions with an insulation layer thereby to suppress the generation of a leakage current and improve the appearance of the solar battery.
CONSTITUTION: A P-type layer 3" is diffused and formed on an N-type semiconductor substrate 3', and insulation layers 6 are formed along the cutting parts for dividing the same into separate solar batteries. In this case, in order to form the insulation layers 6, a thermal diffusion method or an ion injection method is used thereby to diffuse P-type impurities in the layer 3" until they reach the substrate 3' and the width of the diffusion is made into substantially the same as that of the case of ordinary mesa etching. Thereafter, on the front surface and the back surface of the insulation layer there are fitted electrodes 4 and 2, and the layer 6 is cut off from the central part thereof thereby to form a solar battery 7. By this procedure, the layer 6 displays effects similar to those obtained by mesa etching, and generation of leakage current is suppressed and also short circuiting due to the lead terminal is prevented.
