ABSTRACT:
A photoelectric transducer is composed of a photosensitive element 12 and an auxiliary light source 14. In a preferred embodiment, the photosensitive element 12 has an upper transparent electrode 6, a lower transparent electrode 7, a amorphous silicon germanium semiconductor 8, and an transparent glass substrate 11. Incident light 15 irradiates an upper light-receiving surface 9 of the amorphous silicon germanium semiconductor 8 through the upper transparent electrode 6, and the photoelectric current generated by photoelectric conversion at the amorphous silicon germanium semiconductor 8 flows through by the upper transparent electrode 6 and the lower transparent electrode 7. In one embodiment of the invention, the auxiliary light source 14 is a blue light source provided by the right side of the upper transparent electrode 6 to irradiate the photosensitive element 12, which enables selective amplification of the sensitivity of the photoelectric transducer to the incident light in the near infrared region. Furthermore, the amplication factor of the photoelectric current can be changed freely by changing the brightness of the light from the auxiliary light source 14.
