Abstract:
1. A photo-sensing device comprising: a photoelectric conversion semiconductor thin film, a first conductive type semiconductor thin film provided to form an incident light window on one face of the photoelectric conversion semiconductor thin film, multiple electrodes provided over the first conductive semiconductor thin film, partially covering the first conductive semiconductor thin film, a connection wiring that short-circuits the multiple electrodes for output, an insulating film provided on the other face of the photoelectric conversion semiconductor thin film, a first electrode provided on the face of the insulating film that does not contact the photoelectric conversion semiconductor thin film, and a voltage source electrically connected to the connection wiring and the first electrode, wherein, the multiple electrodes and the connection wiring are integrated into one, the voltage source applies an AC voltage between the connection wiring and the first electrode so that a current flows between the connection wiring and the first electrode, the amount of said current generated being dependent upon the amount of an incident light received by the photoelectric conversion semiconductor thin film through the incident light window.
