Abstract:
1. A photoelectric conversion device comprising: a front electrode, a photoelectric conversion layer formed of a semiconductor material, a transparent conductive layer formed of a transparent conductive oxide, a conductive layer formed of a semiconductor material consisting primarily of silicon and having a refractive index higher than the transparent conductive layer, a back electrode formed of a metal material; said front electrode, said photoelectric conversion layer, said transparent conductive layer, said conductive layer, and said back electrode arranged in that order; the conductive layer contactually sandwiched between the transparent conductive layer and the back electrode; the back electrode directly contacting the conductive layer along a plane parallel to the major longitudinal axis of the conductive layer; the refractive index of the conductive layer being 3.4 or higher at a wavelength of 850 nm; and a film thickness of the conductive layer being between 30 nm and 300 nm.
