MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202521085931 A) filed by Pandit Deendayal Energy University, Gandhinagar, Gujarat, on Sept. 10, 2025, for '5-j (junctions), 2-t/10-t (terminals) tandem solar cell.'
Inventor(s) include Dr. Nitesh Kumar Chourasia; Dr. Ritesh Kumar Chourasia; Atish Kumar Sharma; and Dr. Keyur Sangani.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "For the realization of a broader range of solar spectrum to electricity, we have introduce 5-J 2T/10T tandem solar cell showcasing a remarkable performance by employing 2D Dion-Jacobson, methylammonium, ethylammonium, cesium-based perovskites, and compound semiconductors. The proposed tandem solar cell consists of 5 subcells as 5-junctions, and all the subcells are configured in monolithic integration (2-terminal) and mechanical stacking (10-terminal). All the subcells are selected according to their band gaps to ensure a maximum absorption window of the sunlight. All the subcells 1 to 5 have configurations PCBM/(3AMPY)(MA)2Pb3l10/PEDOT:PSS, ZnO/EACsSnGel3/Cu2O, PCBM/MAPbl3/PTAA, TiO2/CsLaTa2Se7/MoO3, CdS/GeTe/NiO, respectively. In the 2-T configuration, the individual performance of subcells 1 to 5 is 12.45%, 14.50%, 12.01%, 5.55%, and 9.17%, respectively. The individual performance of the subcells 1 to 5 in the 10-T configuration is 19.04%, 12.25%, 11.70%, 4.15%, and 10.97%, respectively. Further, the 2-T and 10-T tandem solar cell configurations show 53.56%, and 58.11%, respectively."
