Abstract
We have developed a new donor material, 2,6-di(pyren-1-yl) dithieno[3,2-b:2′,3′-d]thiophene (DDT), consisting of dithieno[3,2-b:2′,3′-d]thiophene (DTT) and pyrene units. The bulk heterojunction (BHJ) device based on DDT?:?C70 = 1?:?4 exhibited an efficient power conversion efficiency (PCE) of 3.60%, under simulated AM 1.5 solar irradiation at 100 mW cm?2.
