Latest Patents

Samuel H Demtsu holds 1 patent for his invention titled "Method of controlling the amount of Cu doping when forming a back contact of a photovoltaic cell." This patent outlines methods for preparing an exposed surface of a p-type absorber layer of a p-n junction for coupling to a back contact in the manufacture of a thin film photovoltaic device. The method includes applying a treatment solution onto the exposed surface defined by the p-type absorber layer of cadmium telluride. Additionally, it involves annealing the device with the p-type absorber layer in contact with the treatment solution to form a tellurium-enriched region in the p-type absorber layer at the exposed surface. The treatment solution comprises a chlorinated compound component that is substantially free from copper, a copper-containing metal salt, and a solvent.
