摘要
Due to the potential for low-cost energy harvesting extensive efforts have been directed at developing bulk heterojunction(BHJ) polymer solar cells(PSCs).[1] Different annealing temperature of Zinc oxide nanoparticles(ZnO NPs), employed during the fabrication of electron transport layers, impact the efficiency of bulk heterojunction polymer solar cells(PSC).The photovoltaic performances of the PSCs based on the donor of poly{4,8-bis[(2-ethylhexyl)oxy]benzo[1,2-b:4,5-b0]-dithiophene-2,6-diyl-alt-3-fluoro-2-[(2-ethylhexyl)carbonyl]thieno[3,4-b]thiophene-4,6-diy(PTB7) and the acceptor of [6, 6]-phenyl-C71-butyric-acidmethyl-ester(PC_(71)BM).The optimized PSC based on PTB7:PC71BM(1:1.5 w/w) exhibited a power conversion efficiency of 7.37% with open-circuit voltage(V_(oc)) of 0.722 V, short-circuit current density(J_(sc)) of 15.38 mA cm-2, and fill factor(FF) of 66.4% at 150℃.The effects of the annealing temperature on photovoltaic performances were illustrated with transmission spectrum, atomic force microscopy, X-ray diffraction and PL spectra, while electrical performance were illustrated with conductivity.Our results indicate that the improved efficiency is due to the optimized electron-transporting interlayer(ETLs) interface, the enhanced transparency and electron transport of the ETLs.
