  • Photovoltaic cell
    Patent number: 4283591
    Abstract: A process for improving the stability of a cadmium chalcogenide/copper chalcogenide photovoltaic cell is disclosed. The improvement comprises positioning a layer of a polymer composition containing electrically conductive particles between the copper chalcogenide layer and the metal electrode such that the metal electrode does not make physical contact with the copper chalcogenide layer.

  • Electroless plating process for glass or ceramic bodies and product
    Patent number: 4259409
    Abstract: Strongly adherent layers of electroless metals on glass or ceramic substrates are obtained by first applying a film of an alkali metal silicate solution containing dissolved therein a catalytically effective amount of nickel, palladium or platinum to the substrate, drying and firing the film onto the substrate and electroless plating the coated substrate.

  • Selective black for absorption of solar energy
    Patent number: 4011190
    Abstract: Improved selective black particles for use in solar receivers are described. The improved selective blacks comprise small particles of a metal having a low emissivity which are coated with a thin layer of an optically dark material having high absorptivity and low reflectivity for solar wavelengths and which is transparent for higher wavelengths in the thermal range. The improved selective black particles can be applied, e.g., as a paint, to any surface suitable for a solar heat receiver.
