A stable copper-modified bipyridine mediator for highly efficient dye-sensitized solar cells
Dye-sensitized solar cells (DSSCs) have garnered significant research attention for their cost-effectiveness, transparency, flexibility, etc. In this work, a copper complex of a bipyridine-modified mediator, [Cu(dmodmbp)2]+/2+, is developed to minimize the loss in fill factor (FF). A DA2 dye, inspired by the structures of previously reported LC4 and LC5 dyes, incorporates cascade acceptors to enhance light absorption and increase the short-circuit current (JSC). These innovations lead to highly efficient DSSCs with an impressive power conversion efficiency (PCE) of 10.2% (JSC = 12.10 mA cm−2, open-circuit voltage [VOC] = 1.11 V, FF = 0.764) as well as a remarkable photostability. A test over 95 days shows that 88% of the initial PCE can be maintained, with VOC, JSC, and FF retaining 98%, 97%, and 93% of their initial values, respectively.
