  • Organovoltaic materials and uses thereof
    Patent number: 12612528
    Abstract: Organic photovoltaics (OPVs) based on a slot-die coated ternary blends for low-intensity light harvesting are disclosed herein. The ternary blends comprise either a N-annulated perylene diimide-based electron acceptor material or an aalkyl-12,13-dihydro[1,2,5] thiadiazolo[3,4e]thieno[2?,3?:4?,5] thieno[2?,3?:4,5] pyrrolo[3,2-g] thieno [2?,3?:4,5]thieno [3,2-b]indole-2,10-diyl)bis(methanylylidene)) bis(3-oxo-2,3-dihydro1H-indene-2,1-diylidene))dimalononitrile) (BTP)-based electron acceptor material, a second acceptor material, and an electron donor material which comprises poly[(2,5-bis(2-hexyldecyloxy) phenylene)-alt-(5,6-difluoro-4,7-di(thiophen-2-yl)benzo[c] [1,2,5]thiadiazole)] (PPDT2FBT). In an aspect, a N-annulated perylene diimide dimer (tPDI2N-EH, PDI) acceptor material was incorporated into a blend of donor polymer material (PPDT2FBT) and fullerene acceptor [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM) material to give ternary bulk heterojunction (BHJ) blends.
