Abstract

Novel MoWO with ZnO nanoflowers was synthesized on multi-walled carbon nanotubes (MW-Z@MWCNTs) through a simple hydrothermal method, and this unique structure was applied as a counter electrode (CE) for dye-sensitized solar cells (DSSC) for the first time. The synergetic effect of ZnO nanoflowers and MoWO on MWCNTs was systematically investigated by different techniques. The amount of MWCNTs was optimized to achieve the best DSSC performance. It was found that the 1.5% MW-Z@MWCNTs composite structure had the highest power conversion efficiency of 9.96%, which is greater than that of traditional Pt CE. Therefore, MW-Z@MWCNTs-based CE can be used to replace traditional Pt-based electrodes in the future.

摘要

通过简单的水热法在多壁碳纳米管（MW-Z@MWCNTs）上合成了带有ZnO纳米花的新型MoWO，并首次将这种独特结构用作染料敏化太阳能电池（DSSC）的对电极（CE）。通过不同技术系统研究了ZnO纳米花和MoWO在MWCNTs上的协同效应。对MWCNTs的用量进行了优化以实现最佳的DSSC性能。发现1.5%的MW-Z@MWCNTs复合结构具有9.96%的最高功率转换效率，高于传统Pt对电极。因此，基于MW-Z@MWCNTs的对电极未来可用于替代传统的Pt基电极。
