Stable dye-sensitized solar cell electrolytes based on cobalt(II)/(III) complexes of a hexadentate pyridyl ligand. Academic Article uri icon


  • 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). Copyright 2013 WILEY-VCH Verlag GmbH & Co.
