In order to enhance photovoltaic performances and to reduce fabrication cost of liquid-junction dye-sensitized solar cells (DSSCs), here we report platinum alloy decorated polyaniline (PANi/MPt, M = Mo, Pd, Co) counter electrodes (CEs) by an electrochemical deposition method. In comparison with pristine PANi electrode, the integration of PANi with MPt alloys markedly enhances the electrocatalytic activity towards 13 reduction reaction. The power conversion efficiencies of 8.08%, 7.26% and 6.83% are determined from DSSCs employing PANi/CoPt, PANi/PdPt, and PANi/MoPt CEs, respectively (C) 2015 Elsevier Ltd. All rights reserved.
