SEMICONDUCTOR OPTICAL ENERGY CONVERSION APPARATUS

摘要

PURPOSE:To permit fine holes or grooves to conduct a current therethrough without lowering open circuit photo electric voltage by providing the fine holes or the fine grooves in an insulating film and directly joinning a semiconductor and an optically transparent conductive material. CONSTITUTION:An insulating film 3 is joinned with a light incident surface of a semiconductor 2, and includes fine holes and/or fine grooves 6 provided for keeping conductivity between the semiconductor 2 and an optically transparent conductive material 4. Diameters of these fine holes and the width of the grooves are specified to be 10-1000Angstrom whereby electric charges produced by light irradiation can be moved without lowering the open circuit photo electric voltage Voc the fine grooves in such a manner, the semiconductor is prevented from being deteriorated to ensure a long if of the same and further ensure a greater phoptoelectric conversion eficiency.
