Abstract

PURPOSE: To enlarge an electricity generating area, by providing electricity generating section series connection electrodes on a side face of an insulating substrate when the first electrodes are produce at a spacing on the insulating substrate capable of being penetrated by visible light and the second electrodes corresponding to the first electrodes across amorphous Si layers are provided over the first electrodes to build a device which has a plurality of electricity generating sections.

CONSTITUTION: The first electrodes 12 of indium oxide, tin or the like are coated at a spacing on an insulating substrate 7 of glass or the like capable of being penetrated by visible light. p-Type and n-type amorphous Si layers are grown on the first electrodes 12 by glow discharge under an atmosphere of a silicon compound such as silane or fluorosilicon. The second electrodes 13 of aluminum are coated on the Si layers so that the second electrodes 13 correspond to the first ones 12. A device having numerous electricity generating sections is thus manufactured. These electrodes 12, 13 are then connected in series with each other. At that time, extending portions 14, 15 of the electrodes are placed on a side face of the substrate 7 and coupled to each other by a connecting part 16. This results in increasing the light reception area of the surface and raising the efficiency of utilization of the semiconductor material.
