ABSTRACT:
An apparatus in which amorphous silicon solar cells are formed on a heat collecting plate. The solar cells are formed by using a superstrate or a substrate. Both a light-permeable superstrate and a metallic substrate are available for use. If the light-permeable superstrate is adopted, metallic electrodes, formed on the side of the heat collecting plate as lower electrodes of the solar cells, are attached to the heat collecting plate through electrically insulating adhesives, provided that the upper surface of the superstrate is exposed against the incident sunlight. The light-permeable superstrate is made of a heat absorbing material transmitting light having a wavelength range which is absorbed by the amorphous silicon layer of the solar cells while absorbing light having a wavelength range which is transmitted through the amorphous silicon layer thereby to convert the light into thermal energy. Alternatively, a heat absorbing layer made of a material having the above-mentioned property may be provided on a transparent superstrate. On the other hand, if the metallic substrate is used, the substrate is also available for the heat collecting plate, or is attached to the heat collecting plate while said heat absorbing layer may be provided on transparent electrodes formed on the upper side of the substrate as upper electrodes of the solar cells.
