染料是染料敏化太阳能电池的核心之一,它的性质直接影响着电池的光电转换效率。多吡啶钌类配合物是目前最有效的染料,但存在合成困难、需要贵金属钌且对环境有一定的污染等缺点,因此近年来纯有机及含廉价金属染料的研究逐渐受到重视。卟啉类染料具有易合成、易修饰及在可见光区有强吸收等特性,这些特性使它在非钌染料的研究中受到青睐。本文从染料结构中的电子给体、电子受体、电子传输通道三方面出发,综述了近几年来关于卟啉类染料的最新研究成果,希望能为研究者设计、合成更优秀的卟啉类染料提供一定的参考。
Dye is one of important factor for dye-sensitized solar cell(DSSC).Due to the synthetic challenge and precious metals needed for multipyridine ruthenium complex dyes,more and more research focus on the pure organic dyes.Porphyrin derivatives as pure organic dyes attract increasing interests because they have lots of merits,such as short synthetic route,easy modification and strong absorption in visible region.In this paper,with analyzing the influences of electron donor,electron transfer channel and electron acceptor,some important results in recent years for porphyrin derivatives as dyes are reviewed.
