摘　　要：We introduce 1-Dodecanethiol(DT)to poly(3-hexylthiophene)(P3HT)/[6,6]-phenyl-C61-butyric acid methyl ester based polymer solar cells as a processing additive.When the amount of DT is 1vol%,the device performance is best.A final power conversion efficiency of 3.1%is achieved,which is an improvement of more than 40%compared to the reference solar cell without DT.To investigate the causes of improvement of the PCE,UV-vis spectroscopy,external quantum efficiency(EQE)is measured and an AFM is used.The enhanced photovoltaic performances are discussed in terms of optical properties and the film morphology.
