MUMBAI, India, Sept. 12 -- Intellectual Property India has published a patent application (202517079262 A) filed by Ics Intelligent Control Systems Ltd Oy, Helsinki, on Aug. 21, for 'an optical structure for enhancing the efficiency of a solar cell.'
Inventor(s) include Rinko, Kari; Tuohioja, Tero; and Pfreundt, Andrea.
The application for the patent was published on Sept. 12, under issue no. 37/2025.
According to the abstract released by the Intellectual Property India: "An optical structure, wherein a first area of a solar cell (102a,b), said first area (106a,b) being a less active edge area of the solar cell (102a,b), is at least partially covered by an overlapping optical layer element (104), wherein said overlapping optical layer structure is configured to at least partially redirect light originally directed towards the first area (106a,b), wherein the redirected light is to be at least partially directed towards a second area (108a,b), optionally including center area, of the solar cell (102a,b), wherein said second area (108a,b) is a more active area than the first area (106a,b), thereby preferably providing, due to enhanced light conversion efficiency, more energy and improved total gain in the solar cell (102a, b) or module comprising the solar cell (102a, b). A method for enhancing the efficiency of a solar cell (102a,b) or a related module and a method for manufacturing an optical structure is further provided."
The patent application was internationally filed on Jan. 24, 2024, under International application No.PCT/FI2024/050030.
