  • Publication number: 20080289683
    Abstract: A method of interconnecting thin-film solar cells formed on a foreign insulating substrate or superstrate is described: the top and bottom layers of the thin-film solar cells having a sheet resistances below 10,000 ?/sq. The method comprises the steps of forming a thin-film solar cell structure comprising at least an n+-type layer (2,3) and a p+ type layer (4) on the foreign substrate/superstrate, and forming one or more electrical contacts (19), each contact being between an n+ type layer on one portion of the substrate/superstrate to a p+-type layer (16) on an adjacent portion of the substrate/superstrate.

  • Patent number: 5646397
    Abstract: A combination comprises a device for receiving and for directing incoming light in a three dimensional manner to at least one predetermined location together with a solar cell. The device has two light reflecting surfaces and a total internal reflection surface. In operation, the total internal reflection surface transmits the incoming light into the device and totally internally reflects the light reflected from the surface which is incident at its surface at an angle within the range for total internal reflection. The reflection surfaces are operatively disposed with respect to one another so as to perform the function of a receiver/director by directing incoming light in a three dimensional manner to the rear surface of the solar cell.
