  • Method of making a transparent conductive oxide layer and a photovoltaic device
    Patent number: 8476105
    Abstract: In one aspect of the present invention, a method is provided. The method includes disposing a substantially amorphous cadmium tin oxide layer on a support; and thermally processing the substantially amorphous cadmium tin oxide layer in an atmosphere substantially free of cadmium from an external source to form a transparent layer, wherein the transparent layer has an electrical resistivity less than about 2×10?4 Ohm-cm. Method of making a photovoltaic device is also provided.

  • CADMIUM DOPED TIN OXIDE BUFFER LAYER FOR THIN FILM PHOTOVOLTAIC DEVICES AND THEIR METHODS OF MANUFACTURE
    Publication number: 20130133731
    Abstract: Methods for forming a resistive transparent buffer layer on a substrate are provided. The method can include depositing a resistive transparent buffer layer on a transparent conductive oxide layer on a substrate. The resistive transparent buffer layer can comprise a cadmium doped tin oxide that has an as-deposited stoichiometry where cadmium is present in an atomic amount that is less than 33% of a total atomic amount of tin and cadmium. Zinc may also be provided in the resistive transparent buffer layer in certain embodiments. Additionally, thin film photovoltaic devices having such resistive transparent buffer layers are provided.
