MoS2与碳材料复合对电极在染料敏化太阳能电池的应用研究

As one of the new kind solar cells, dye-sensitized solar cell has been discovered for more than 20 years.So far, Pt thin film has been the most commonly used counter electrode in traditional DSSCs. Unfortunately, its high cost, poor stability in corrosive electrolytes, and less reserves hinder its commercial application. It is necessary to find high efficient, cheap and durable counter electrode. This project aims to composite high catalytic activity MoS2 and high electrical conductivity carbon material. We plan to investigate: (1) the preparation method of MoS2 composite different carbon material; (2)the catalytic activity performance of composite counter electrode for iodine electrolyte; (3) how the variety and microstructure of carbon material effect the property of cells. This project will help the commercial application of dye-sensitized solar cell.

作为新型太阳能电池的一种，染料敏化太阳能电池问世已经有20多年，目前传统染料敏化太阳能电池多以铂作为对电极材料，但铂价格昂贵、储量很少、耐腐蚀性差，严重限制了染料敏化太阳能电池的产业化发展。寻找新型高效、廉价、长寿的对电极是极具意义的工作。此项目旨在通过将高催化活性的MoS2与高导电性的碳材料进行复合，深入探索：（1）硫化钼与不同碳材料的复合材料对电极制备方法探究；（2）复合对电极在电池中对碘系电解液的催化还原氧化作用规律；（3）碳材料种类、微观结构不同对电池性能的影响，从而推进染料敏化太阳能电池的商业化进程。
