合成了聚吡咯（PPy）纳米粒子并将其涂覆在导电 FTO 玻璃上以构建用于染料敏化太阳能电池（DSSC）的 PPy 对电极。扫描电镜图像显示，多孔、粒径在40-60 nm的PPy均匀、紧密地覆盖在Fro玻璃上。 I-2/I-体系的循环伏安图测量表明，与Pt电极相比，PPy电极具有更小的电荷转移电阻和更高的I-2/I-氧化还原反应电催化活性。具有PPy对电极的DSSC的整体能量转换效率达到7.66%，比具有Pt对电极的DSSC高11%。优异的光电性能、简单的制备过程和低廉的成本使PPy电极成为DSSCs中可靠的替代品。 (C) 2008 年由 Elsevier B.V. 出版
Polypyrrole (PPy) nanoparticle was synthesized and coated on a conducting FTO glass to construct PPy counter electrode used in dye-sensitized solar cell (DSSC). Scanning electron microscope images show that PPy with porous and particle diameter in 40-60 nm is covered on the Fro glass uniformly and tightly. Cyclic voltammograms of I-2/I- system measurement reveals that the PPy electrode has smaller charge-transfer resistance and higher electrocatalytic activity for the I-2/I- redox reaction than that Pt electrode does. Overall energy conversion efficiency of the DSSC with the PPy counter electrode reaches 7.66%, which is higher (11%) than that of the DSSC with Pt counter electrode. The excellent photoelectric properties, simple preparation procedure and inexpensive cost allow the PPy electrode to be a credible alternative used in DSSCs. (C) 2008 Published by Elsevier B.V.
