A high-performance solution-processed small molecule: alkylselenophene-substituted benzodithiophene organic solar cell |
초록 |
A solution-processed alkylselenophene-substituted benzodithiophene (BDT) small molecule, namely, BDTSe-TTPD, with broad absorption and suitable energy levels was synthesized. The widely used solvents o-dichlorobenzene (o-DCB), chlorobenzene (CB) or chloroform (CF) were used as the spin-coating solvent, to fabricate efficient photovoltaic devices with BDTSe-TTPD as the donor material and PC71BM as the acceptor. Devices made from a CF solution demonstrated better performance in terms of short-circuit current, fill factor and power conversion efficiency, as compared to the devices made from the o-DCB and CB solutions. Finally, by optimizing the thickness of the active layer, a power conversion efficiency of 4.37% was achieved on devices with an area of 0.09 cm2, under 100 mW cm_2 of simulated AM 1.5 irradiation. |
