半导体敏化太阳能电池在过去的几年中吸引了越来越多的兴趣。从相当低的转换效率开始，这些已经非常迅速地增长到大约4- 5%的值。该观点分析了三个方面的优化，以提高电池性能，（i）材料，不仅包括光吸收材料，而且还包括电子和空穴导体和反电极，（ii）通过表面处理控制复合和能带排列，以及（iii）开发具有增强的光捕获和收集性能的吸收纳米复合材料。我们认为，这些关键的主题可以促进重大突破的设计和开发的半导体敏化太阳能电池。
Semiconductor sensitized solar cells have attracted growing interest in the past few years. Starting from quite low conversion efficiencies, these have grown very rapidly to values of around 4-5%. This Perspective analyzes the optimization of three aspects toward an increase in cell performance, (i) materials, including not only light-absorbing materials but also electron and hole conductors and counter electrodes, (ii) control of recombination and band alignment by surface treatments and (iii) development of absorbing nanocomposites with enhanced light-harvesting and collecting properties. We argue that these key topics could promote major breakthroughs in the design and development of semiconductor-sensitized solar cells.
