Abstract
Polymer photovoltaic solar cells using poly (2,6-bis(3-alkylthiophen-2-yl)dithieno-[3,2-b;2′,3′-d]thiophene) (PBTDT) as the donor is demonstrated. The UV–vis spectra show that PBTDT has strong absorption in the visible spectrum. By adjusting the ratio of PBTDT to [6,6]-phenyl C61-butyric acid methyl ester (PCBM) and optimizing the annealing temperature, the PBTDT-based polymer solar cells show a power conversion efficiency of 0.42% under 100 mW/cm2 AM1.5G simulated sunlight.
