Photoelectric converter and its preparation

Abstract

Abstract PURPOSE:To integrate an entire system and reduce the costs of a device by forming plural first electrodes of the same shape on an insulating substrate, depositing a semiconductor layer with generates light electromotive force over the electrodes, covering the layer with a transparent second electrode and providing a reverse current preventing diode on the same substrate. CONSTITUTION:On an insulating substrate 1 consisting of a glass-epoxy composite material, etc., plural first electrodes 2 with a two-layer construction of Cr and Al are formed, while a monocrystalline, polycrystalline or amorphous semiconductor layer 3 with junctions of PN, PIN, etc. is deposited all over the surface for generating light electromotive force and the entire surface is covered with a transparent second electrode 4. Then the electrodes 2 are divided into separate regions by etching, both end electrodes 2 are used for first and second bus lines 5 and 9, the part between them is used for photoelectric converters 6 and 7, excepting one part of them being used for a reverse current preventing diode 8. The devices 6 and 7 are connected in series, and 7 and 8 are connected.
