PURPOSE:To minimize a drop in an output voltage due to a reduction in the potential energy by a method wherein a photodetecting face electrode and a semiconductor film which are faced by sandwiching an insulating film are brought into partially direct contact with each other. CONSTITUTION:A photodetecting face electrode 1, a light-transmitting insulating film 2, a semiconductor film 3 and a rear electrode 4 are arranged in succession from the light-incident side on one main face of a substrate 5; the photodetecting face electrode 1 and the semiconductor film 3 which are faced by sandwiching the insulating film 2 are brought into partially direct contact with each other via through holes 6. By this setup, an electric surrent flows in such a way that it is concentrated on partially direct contact parts of the photodetecting face electrode 1 and the semiconductor film 3; accordingly, although the potential energy is reduced locally at the direct contact parts, a defect level is filled by a concentrated carrier; it is possible to minimize a drop in an output voltage due to a reduction in the potential energy and to reduce a series resistance component. |
