Abstract

Exchanged: The organic radical 2-azaadamantan-N-oxyl (AZA; see picture) is found to be a stable and highly reactive redox mediator in dye-sensitized solar cell (DSSC) electrolytes. This radical has an appropriate redox potential and significantly high values for the diffusivity, heterogeneous electron-transfer rate, and electron self-exchange reaction rate. In a DSSC the AZA-based electrolyte achieves an excellent photovoltaic performance.
