In this study, P3HT and PCBM were used as donor and acceptor materials for polymer solar cells. The standard device was constructed of ITO / PEDOT:PSS / P3HT:PCBM / Al and the power conversion efficiency of 2% was achieved under AM1.5G 100mW/cm2 illumination.
In order to increase the hole transporting ability, we used PEDOT nanorods with high conductivity as an anode interlayer between the PEDOT:PSS and the P3HT:PCBM layer, with a configuration of ITO / PEDOT:PSS / PEDOT nanorods / P3HT:PCBM / Al.
According to experimental results. PEDOT nanorods dispersed well on the PEDOT:PSS surface through the spin-coating process. As the concentration of PEDOT nanorods 1wt% casting film, the conductivity of anode buffer layer raised about two times and the power conversion efficiency of device reached 2.63%. The short-circuit current and the power conversion efficiency of the polymer solar cell containing 1wt% PEDOT nanorods were obtained about 170% and 30% increasement, respectively.
In conclusion, it is quite useful to apply the PEDOT nanorods into polymer solar cells as an interlayer. The improvement in the short-circuit current which resulted in an enhancement of the power conversion efficiency originated from the increased conductivity of the buffer layer.
