MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122973 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Dec. 5, 2025, for 'high-efficiency solar cell with optimized electron transport layer.'
Inventor(s) include Dr. Dharmendra Kumar Bal; Dr. Kuldeep Roy; Soham Kavathekar; Suved Malokar; and Sowmyan Nagaraj.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a solar cell device comprising a transparent conductive front contact layer comprising fluorine-doped tin oxide, a buffer layer comprising zinc selenide disposed on the front contact layer, an absorber layer comprising cadmium telluride disposed on the buffer layer, an electron transport layer comprising cesium bismuth silver iodide (Cs2BiAgI6) disposed on the absorber layer, and a metal back contact layer disposed on the electron transport layer, wherein the solar cell device achieves a power conversion efficiency exceeding 27% under standard test conditions. The method (100) includes initializing a SCAPS-1D simulation environment, defining a base solar cell structure, executing comparative analysis of electron transport layer materials, selecting cesium bismuth silver iodide, systematically varying layer thicknesses, and generating an optimized solar cell configuration achieving power conversion efficiency exceeding 27.99%."
