Abstract

Abstract : The crucial role of tert -butylpyridine and lithium bis(trifluoromethanesulfonyl)imide in the performance of sustainable "full-copper" DSSCs. Abstract : The use of a copper(i ) dye, bearing a 2, 9-dimesityl-1, 10-phenanthroline and a 6, 6′-dimethyl-2, 2′-bipyridine-4, 4′-dibenzoic acid, was investigated in DSSCs with various electrolyte solutions based on two different redox mediators, namely the common I − /I3 − couple and an interesting copper electron shuttle. The experimental results provide evidence of the importance of the redox mediator concentration and the crucial role of additives such as 4- tert -butylpyridine and lithium bis(trifluoromethanesulfonyl)imide in the performance of sustainable "full-copper" DSSCs, consolidating the way to DSSCs with Earth-abundant components.
