Abstract

Abstract A photoelectric converter comprises a semi­conductor transistor having a main electrode region of one conductivity type semiconductor and a control electrode region of an opposite conductivity type semiconductor, and a capacitor for controlling a potential of the floating control electorde region. Carriers generated by a light are stored in the control electrode region by controlling the potential of the control electrode area through the capacitor. The stored voltage is read and stored carriers are refreshed. On an unnucleation surface (S NDS ) of said light transmissive substrate, a nucleation surface (S NDL ) of a heterogeneous material having a sufficiently higher nucleation density than that of the material of unnucleation surface and a sufficiently small area to permit growth of single nuclear of the deposite surface is formed. A single crystal region is grown around the single nuclear formed in the nucleation surface (S NDL ). And a photoelectric conversion cell is formed is the single crystal region.
