A photovoltaic structure having an electrode of a glass substrate coated with a high work function metal to which a film of a combination of a non-conjugated conductive polymer and an electron acceptor such as fullerene, carbon, iodine, or potassium iodide is applied. The structure has a second electrode of a low work function metal that has been coated on the glass substrate. This glass substrate with the low work function metal is applied to the film. Among the non-conjugated polymers are polyisoprene, poly(β-pinene), cis-polyisoprene, styrene-butadiene-rubber copolymer, polynobornene and polyalloocimene. When light strikes this photovoltaic structure it is capable of generating electric voltage greater than 100 mV for a light intensity of about 5 mW/cm2.
