Abstract
A photoelectric conversion device in photoelectric conversion in a light-absorption region in a crystalline silicon substrate is efficiently performed is provided. In the photoelectric conversion device, a light-transmitting conductive film which has a high effect of passivation of defects on a silicon surface and improves the reflectance on a back electrode side is provided between the back electrode and the crystalline silicon substrate, The light-transmitting conductive film includes an organic compound and an inorganic compound. The organic compound includes 4-phenyl-4'-(9-phenylfluoren-9-yl)triphenylamine. The inorganic compound includes an oxide of a metal belonging to any of Groups 4 to 8 of the periodic table.
