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).
