MUMBAI, India, Nov. 2 -- Intellectual Property India has published a patent application (202617091935 A) filed by Cnbm Research Institute For Advanced Glass on July 29, 2026, for Improved Back Contact Layer For Photovoltaic Modules And Manufacturing Method Thereof.
Inventors include Palm, Joerg; and Lomuscio, Alberto.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: The present invention discloses an improved back contact layer for photovoltaic modules and a manufacturing method thereof, which are applied to CIGSS photovoltaic modules. The back contact layer is located between a back electrode layer and a CIGSS absorber layer. The back contact layer includes: a reflective layer, deposited on a carrier substrate, and comprising a bottom layer as a metal layer and a first intermediate layer, where the bottom layer adopts a material with good conductivity for contacting with the substrate, and the first intermediate layer adopts a material as a TCO layer; a protective layer, deposited on the reflective layer, and comprising a second intermediate layer and a top layer, where the CIGSS absorber layer is arranged upon the protective layer, and the top layer adopts a material with good conductivity for forming Ohmic contact with the CIGSS absorber layer.
