The identification of an efficient and stable redox mediator is of paramount importance for commercialization of dye-sensitized solar cells (DSCs). Herein, a new class is reported of copper complexes containing diamine-dipyridine tetradentate ligands (L1 = N,N’-dibenzyl-N,N’-bis(pyridin-2-ylmethyl)ethylenediamine; L2 = N,N’-dibenzyl-N,N’-bis(6-methylpyridin-2-ylmethyl)ethylenediamine) as redox mediators in DSCs. Devices constructed with [Cu(L2)]2+/+ redox couple afford an impressive power conversion efficiency (PCE) of 9.2% measured under simulated one sun irradiation (100 mW cm-2, AM 1.5G), which is among the top efficiencies reported thus far for DSCs with copper complex-based redox mediators. Remarkably, the excellent air, photo, and electrochem. stability of the [Cu(L2)]2+/+ complexes renders an outstanding long-term stability of the whole DSC device, maintaining ?90% of the initial efficiency over 500 h under continuous full sun irradiation This work unfolds a new platform for developing highly efficient and stable redox mediators for large-scale application of DSCs.
