Abstract

Energy conversion: A cobalt redox mediator, [Co(bpyPY4)]^2+/3+, based on a hexadentate polypyridyl ligand, was developed. Dye-sensitized solar cells (DSCs) made with this redox mediator showed improved stability and slightly higher efficiencies compared to [Co(bpy)₃] ^2+/3+-based devices. Long-term stability evaluation of DSCs based on [Co(bpyPY4)]^2+/3+ revealed excellent stability under full irradiation conditions (see picture).
