Using an aqueous electrolyte based on a tris(1,2-diaminoethane)cobalt(ii/iii) redox mediator in p-type dye-sensitized solar cells gives energy conversion efficiencies of up to 1.6% under AM 1.5 simulated sunlight.
We report the synthesis of dyes with recognition sites that facilitate pseudorotaxane formation and implementation into a p-type DSSC where the ring acts as a redox mediator.
