Efficient photovoltaic (PV) cells based on regioregular poly(3-hexylthiophene) (P3HT):fullerene derivative [6,6]-phenyl-C-61 butyric acid methyl ester (PC61BM) composites have been fabricated by using solution-processed molybdenum oxide (MoO3) as an anode buffer layer. The influence of solution-processed MoO3 anode buffer layer on the device performance of P3HT:PCBM PV cells is investigated as compared to the PV cells with different anode buffer layers including water-soluble poly(ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and the thermally evaporated MoO3. It is found that the performance of the PV cell with solution-processed MoO3 anode buffer layer is comparable or higher than the devices using PEDOT:PSS or thermally evaporated MoO3 as the anode buffer layer. The power conversion efficiency of PV cell with solution-processed MoO3 anode buffer layer reaches 3.14% under AM1.5G 100 mW/cm(2) illumination. (C) 2010 Elsevier B.V. All rights reserved.
