摘要：
A novel MoS2/PEDOT-PSS counter electrode (CE) is proposed and used for dye sensitized solar cells (DSCs). The MoS2/PEDOT-PSS composites were facilely obtained from the mechanical mixture of hydrothermal synthesized MoS2 nanomaterial and poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) aqueous solution, and the composites are compatible to low temperature and cost-effective screen-printing fabrication technique. DSC with MoS2/PEDOT-PSS CE exhibits comparable power conversion efficiency and fill factor to the DSC with conventional Pt CE. The good photovoltaic performance of DSC using MoS2/PEDOT-PSS CE is primarily derived from the high electrocatalytic activity of nanosized MoS2 and the high conductive feature of PEDOT-PSS. These results reveal the potential application of MoS2/PEDOT-PSS composite in the use of low-cost, printable and efficient Pt-free CEs. (C) 2014 Elsevier B.V. All rights reserved.
