ABSTRACT:
A multiple cell photovoltaic device includes first and second serially connected solar cells and a conductive or dielectric selective reflection film therebetween. The thickness of the selective reflection film is chosen to reflect short wavelength light which may be absorbed by the second solar cell and to transmit long wavelength light which is not absorbed by the second solar cell and may be absorbed by the first solar cell. When the selective reflection film comprises a dielectric material, apertures are provided in the selective reflection film for serial electrical connection of the two cells.
