染料敏化太阳能电池（DSSC）提供了一个技术上和经济上可行的替代概念，目前的p-n结光伏器件。与传统的硅系统相比，半导体承担光吸收和电荷载流子传输的任务，这两个功能在DSSC中是分开的。具有宽吸收带的敏化剂与中孔或纳米晶形态的宽带隙半导体膜的结合使用允许收获大部分阳光。这些器件具有良好的前景，可以达到基于液体电解质的染料敏化太阳能电池的转换效率，目前为11%。在这篇文章中，我们提出了该领域的当前状态，我们的审查领域被限制在有机分子空穴导体的讨论，这已经证明了迄今为止最好的性能。
The dye-sensitized solar cell (DSSC) provides a technically and economically viable alternative concept to present-day p-n junction photovoltaic devices. In contrast to conventional silicon systems, where the semiconductor assumes both the task of light absorption and charge carrier transport, these two functions are separated in DSSCs. The use of sensitiziers having a broad absorption band in conjuction with wide-bandgap semiconductor films of mesoporous or nanocrystalline morphology permits harvesting a large fraction of sunlight. There are good prospects that these devices can attain the conversion efficiency of liquid-electrolye-based dye-sensitized solar cells, which currently stands at 11%. In this article, we present the current state of the field, the realm of our review being restricted to the discussion of organic molecular hole conductors, which have demonstrated the best performance to date.
