MUMBAI, India, July 24 -- Intellectual Property India has published a patent application (202641064142 A) filed by Bharathiar University on May 21, 2026, for Perovskite Solar Cell For Energy Harvesting And Its Method Thereof.
Inventors include T. C. Sabari Girisun; J. Kawya; and Nithin Xavier.
The application for the patent was published on July 17, 2026, under issue no. 29/2026.
Abstract: The perovskite solar cell [100] for broadband energy harvesting comprises of a plurality of stacked layers not limited to FTO [ 1 06], a compact layer of Titanium dioxide (c-TiOz) [105], a mesoporous electron transport layer [104] of titanium dioxide, a photoactive perovskite layer [103] oftri-cation mixed halide material, a hole transport layer [1 02] of spiro-OMeT AD organic material and a metal contact layer [ l 0 I]. The method of developing the modified hybrid based perovskite solar cell [ 1 00] lies in the fabrication of the electron transport layer [I 04]. The mesoporous electron transport layer of titanium dioxide [I 04] is modified by adding up-converters ofY z03: Yb, Erin the TiOz layer at four different weight percentages (1-7% wt). The up-converters in the cell promotes the photon absorption in the active layer by converting near-infrared photons into visible photons. This enhances the absorption efficiency not limited to the range from 7 to 13 %. 2026410
