Abstract

Chemistry Chemistry, Multidisciplinary Physical Sciences Science & Technology
Two new D-pi-A sensitizers (L101 and L102) incorporating 5H-[1,2,5]thiadiazolo [3,4-f] isoindole-5,7(6H)-dione and 6H-pyrrolo[3,4-g]quinoxaline-6,8(7H)-dione core structures were synthesized and tested in liquid dye-sensitized solar cells (DSCs). L102 achieved a promising power conversion efficiency (PCE) of 6.2% (AM 1.5, 100 mW cm(-2)).
