摘要: Abstract Polymer nano-composite composed of poly(3,4-ethylenedioxythiophene):poly (styrenesulfonate) and TiO 2 nano-particles was deposited on fluorine-doped tin oxide substrate applied as an alternative to Au counter electrode quantum dot-sensitized solar cell (QDSC). It became surface-richer with the increase in nano-particle amount so that catalytic reaction increased by widened interface. Electrochemical impedance spectroscopy cyclic voltammetry clearly demonstrated enhancement polymer electrode. A QDSC based showed 0.56 V V OC , 12.24 mA cm −2 J SC 0.57 FF, 3.87% efficiency this photovoltaic performance higher than (3.75%).
