Research Abstract |
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.
