  • Electrode for photovoltaic cell
    Patent number: 4260429
    Abstract: In a photovoltaic cell which comprises a first electrode, a first layer of cadmium sulfide, a second layer of cuprous sulfide forming a barrier junction with said first layer, and a second electrode, the improvement wherein said second electrode is formed by coating a conducting metal wire with a solid polymer containing electrically conductive particles, and attaching the coated wire to the cuprous sulfide layer by the application of moderate heat and/or pressure.

  • 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.
