Analysis of charge-transfer mechanism of the dye-sensitized photovoltaic devices using iodine-free electrolyte

本研究的重点是染料敏化太阳能电池（DSSC）的低碘浓度电解质组成。碘是DSSC电解质的重要组成部分，但即使在本研究中使用的低碘浓度下，也可以获得相当的能量转换效率。当使用低碘浓度电解质时，基于导电塑料基板的DSSC具有高耐久性，并且光伏性能显示出对温度的非常小的依赖性。

This research is centered on the electrolyte compositions of low iodine concentrations for dye-sensitized solar cells(DSSCs). Iodine is an essential component of a DSSC electrolyte, but even at the low iodine concentrations used in this research, comparable energy conversion efficiencies can be obtained. When the low iodine concentration electrolyte is used, the DSSCs based on conductive plastic substrates have high durability, and the photovoltaic performance shows a very small dependence on temperature.
