Abstract
A photoelectric conversion device includes a light transmissive substrate having a deposition surface and a bottom surface. The bottom surface receives light and passes it through the substrate. A heterogeneous deposition surface is formed on the substrate deposition surface and has a nucleation density higher than the nucleation density of the substrate deposition surface. The heterogeneous deposition surface also has an area dimensioned to permit growth of a single nucleus of a single crystal material. A photoelectric conversion collector is formed of the single crystal material grown on the heterogeneous deposition surface. The collector receives light passed through the substrate bottom surface. Photoresponsive transistor elements are formed in and on the collector for outputting a signal corresponding to the light received by the collector through the bottom of the light transmissive substrate. Thus, electrical wiring and transistor elements are formed on the top of the collector, away from the collector surface which receives the light.
