The dye-sensitized solar cell (DSC) as a low price photovoltaic technology has attracted widespread attention in recent years. During its progress to practical application, replacement of the liquid electrolytes by solid-state ones has been found to be necessary. Alternative solid-state electrolytes have thus been developed. This review deals with the recent progress of different solid-state electrolytes on DSCs. In particular, representative examples are highlighted with the results of our solid-state composite electrolytes based on addition compounds.
