Abstract
PURPOSE: To prevent PN junction short-circuit generation at a production time to improve yield by forming a diffusion layer or an oxide film layer on the surface in the ingot state before cutting off a prescribed-thickness plate body from the columnar single-crystal ingot, and cutting off the plate body after that.
CONSTITUTION: Impurity of a prescribed concentration is beforehand diffused in semiconductor materials such as Si, Ge, GaAs, GaP, CdS and CdTe used for a solar battery, and they are made into a columnar or polyangularprism single-crystal ingot. Next, it is heated in an atomosphere of the same conductive-type impurity as included impurity in this state, and high-impurity layer 11 is formed at a uniform depth from the surface by diffusion. After that, this ingot is cut off into prescribed- thickness plate body 10 and is subjected to heat treatment in the opposite conductive-type atmosphere to provide cinductive layer 12 and generate PN junction. Next, one layer 12, which becomes a light receiving face, and layer 11 on the side face are covered with resistor 13, and the other layer 12 is removed by etching, and electrodes 14 and 15 are fitted onto the surface and the reverse face respectively.
