PURPOSE:To provide a method for manufacturing an inexpensive photoelectromotive force device. CONSTITUTION:A high-purity silicon layer 2, island-like n<+>-type amorphous silicon films 3 which are arranged on the layer 2 at prescribed intervals, and p<+>-type amorphous silicon film 4 are successively formed on a low-purity silicon substrate 1. The high-purity silicon layer 2 of such constitution is used as an optical active layer. |
