Latest Patents
One of Nakada's key patents is for a solar cell substrate made of stainless steel foil. This substrate contains 7% to 40% by mass chromium and has a coefficient of linear expansion of 12.0×10⁻⁶/°C or less at temperatures ranging from 0°C to 100°C. The thickness of the substrate ranges from 20 µm to 200 µm. The patent outlines a method for manufacturing this substrate, which involves a preparatory heat treatment for stress relief in a specific atmosphere. The process includes forming a back-contact made of a molybdenum layer on the treated stainless steel foil, or applying an insulating coating followed by the back-contact formation. An absorber layer made of Cu(InGa)Se is then formed on the back-contact through a coating formation heat treatment.
