ABSTRACT:
A photoelectric element includes a first region having a light-receiving surface. A second region having a short side length not greater than twice the minority carrier diffusion length of the first region is provided on at least one portion of the first region to form a photovoltaic mechanism in conjunction with the first region. A barrier layer is provided to cover at least those portions of the light-receiving surface of the first region not covered by the second region, and a transparent conductive film is provided on the barrier layer and electrically connected to at least one second region. The voltage of the second region generated by incident light is applied through the transparent conductive film to the light-receiving surface of the first region to produce an electric field in the direction inducing majority carriers.
