Abstract:
A photoelectric conversion device comprising:a transparent substrate having a first principal surface and a second principal surface that are parallel to each other; an antireflection film formed on the first principal surface; a transparent conductive film formed on the second principal surface; at least one photoelectric conversion unit formed on the transparent conductive film; and a back electrode formed on the photoelectric conversion unit, wherein the antireflection film contains fine particles with an average particle diameter in a range of 0.01 &mgr;m to 1.0 &mgr;m and has an uneven surface derived from the fine particles, the transparent substrate has a light transmittance of 75% or more in a wavelength region in a range of 800 nm to 900 nm when measured with the transparent conductive film formed thereon, and at least one of the photoelectric conversion units includes a thin film of semiconductor material having a band gap of 1.85 eV or less as a photoelectric conversion layer, the at least one photoelectric conversion unit including an amorphous silicon based photoelectric conversion unit having an amorphous silicon based thin film as the photoelectric conversion layer and a crystalline silicon based photoelectric conversion unit having a crystalline silicon based thin film as the photoelectric conversion layer, the two photoelectric conversion units being stacked in this order from a side of the transparent conductive film.
