Role of lithium and co-existing cations in electrolyte to improve performance of dye-sensitized solar cells

摘要

The performance of dye-sensitized solar cells (DSSCs) with an electrolyte including mixed cations was evaluated, and the relevant carrier dynamics were investigated by the heterodyne transient grating method. The performance of the DSSCs showed maximum conversion efficiency for an Li ~(+) cation ratio of 75% with 25% other cations.
