摘 要
本论文简单介绍了染料敏化太阳能电池(DSSCs)对电极的最新进展。对电极对染料敏化太阳能电池的光电转换效率和制备成本有很大的影响,但是铂对电极的成本昂贵限制了DSSCs的大规模应用,炭对电极因其成本低、还原活性高、光伏性能好等特点受到了广泛关注。湘潭大学谭松庭教授课题组对炭气凝胶、炭黑和活性炭在不锈钢网基底上制备了柔性的染料敏化太阳能电池对电极性能做了测试,通过光伏性能测试来研究对电极的光物理与光化学性质。结果表明,具有较高比表面积和中孔含量炭气凝胶具有远比炭材料如炭黑、石墨等更好的催化还原活性,其催化活性甚至还超过了比表面积是两倍于炭气凝胶的活性炭制备的对电极,这说明炭气凝胶的中孔结构和高孔隙率更有利于 I3 在电解质和对电极界面处的扩散,从而提高 I3- 在对电极上的还原速度。所以,炭气凝胶的中孔含量是影响炭气凝胶还原活性的主要因素。本实验为了获得更大中孔含量和比表面积的炭气凝胶做了如下研究:
1.将间苯二胺、三聚氰胺分别直接加入炭气凝胶的聚合反应,并在钢丝网上制成柔性对电极,通过光伏特性、孔径分布等测试来比较得出能更好的获得较大中孔含量和比表面积的炭气凝胶的方法。
2.将间苯二胺、三聚氰胺分别配成不同浓度的溶液,将未掺杂氮的炭气凝胶放入浸泡,通过测试来比较高效能炭气凝胶柔性对电极的制备方法。

This paper simply introduces the DSSC (DSSCs) the latest progress of electrode. The electrode for DSSC photoelectric conversion efficiency and preparation costs, but have great influence on the costly platinum electrode DSSCs large scale application of limits of electrode, carbon reduction due to its low cost, high activity, pv performance is good wait for a characteristic received widespread concern. Our TanSongTing xiangtan university professor of carbon aerogels, carbon black and activated carbon in stainless steel nets on the preparation of flexible substrate for DSSC performance was testing of electrode, through the pv performance testing to study the electrode light physics and photochemical properties. Results show that, with high specific surface area and content of carbon aerogels holes than carbon materials with such as carbon black, graphite better catalytic reduction activities, its catalytic activity even than the surface area is more than twice the preparation of carbon aerogels of electrode of activated carbon, suggesting the carbon aerogels in pore structure and high porosity is more advantageous to the I3  in electrolyte and the spread of the interface between the electrode, so as to improve the I3 - in the reduction of electrode speed. So, the holes in carbon aerogels affect carbon aerogels content is the main factor reduction activities. This experiment in order to obtain more big hole content and specific surface area of the carbon aerogel made the research:
1. Between benzene 2 amine, melamine directly join carbon aerogels respectively in the polymerization reaction, and made of electrode wire online, through flexible photovoltaic characteristics, pore size distribution test to compare such that can better get bigger than the surface area of the hole contents and the methods of carbon aerogels.
2. Between benzene 2 amine, melamine made up with different concentrations of respectively, will not doped solution of nitrogen, carbon aerogels tests to soak in comparative efficiency of electrode carbon aerogels preparation methods of flexible.
