摘要:
摘要： In this work, we demonstrate a new kind of Pt-free counter electrode for dye-sensitized solar cells（DSCs）. Polypyrrole-cobalt-carbon（PPY-Co-C） nanocomposites, with the advantages of low cost and simple preparation, show favorable catalytic activity in promoting tri-iodide reduction. The DSC composed of the PPY-Co-C nanocomposite electrode exhibits an acceptable energy conversion efficiency of 6.01%, a considerable short-circuit photocurrent of 15.33 mA cm-2, and a low charge-transfer resistance of 1.5 Ω cm2. The overall performance of PPY-Co-C is superior to the carbon counterparts and comparable with the platinum reference, rendering them efficient and promising counter electrode materials for DSCs. 其他題名： Sci.
