我们提出了一种固态染料敏化太阳能电池（SDSC）的优化研究，包括介孔氧化锡光阳极渗透与聚（3-己基噻吩-2，5-二基）（P3 HT）空穴导体和敏化与有机染料。我们选择了SnO（2）和P3 HT，因为它们具有高电荷载流子迁移率和电导率，但由于高漏电流和低分流电阻，因此排除了传统的器件配置。为了使通过FTO阳极的“空穴漏电流”最小化，我们采用了双致密层结构，并且为了使银阴极处的“电子漏电流”最小化，我们开发了用于沉积最佳P3 HT“覆盖层”的方案。在优化电池制造之后，电子寿命显著增加，并且太阳能电池表现出超过1%的模拟AM1.5全太阳太阳能转换效率。
We present an investigation on the optimisation of solid-state dye sensitized solar cells (SDSCs) comprising mesoporous tin oxide photoanodes infiltrated with poly(3-hexylthiophene-2,5-diyl) (P3HT) hole conductor and sensitized with an organic dye. We chose both the SnO(2) and P3HT for their high charge carrier mobilities and conductivities, but as a result preclude conventional device configurations because of high leakage current and low shunt-resistance. To minimize the "hole leakage current" through the FTO anode, we employed a double compact layer structure, and to minimize "electron leakage current" at the silver cathode, we developed a protocol for depositing an optimal P3HT "capping layer". After optimisation of cell fabrication, the electron lifetime is increased considerably and the solar cells exhibited simulated AM1.5 full sun solar power conversion efficiencies in excess of 1%.
