ABSTRACT:
A semiconductor device includes laminated photoelectric conversion elements each having a semiconductor thin film carrying out the photoelectric conversion, the respective semiconductor thin film having a relationship L.ltoreq.1/.alpha.(.lambda.) when incident light is of a wavelength .lambda., the semiconductor thin film is of an absorbtion coefficient .alpha.(.lambda.) with respect to the light of the wavelength .lambda. and the carrier collecting length is L, whereby the optimum combination of the incident light wavelength and the sensitivity of the device can be obtained to realize a high photoelectric conversion efficiency.
