In tandem : Employing a molecular dyad and a cobalt‐based electrolyte gives a threefold‐increase in open‐circuit voltage ( V OC ) for a p‐type NiO device ( V OC =0.35 V), and a fourfold better energy conversion efficiency. Incorporating these improvements in a TiO 2 /NiO tandem dye‐sensitized solar cell (TDSC), results in a TDSC with a V OC =0.91 V (see figure; CB=conductance band, VB= valence band).
