A molecular photosensitizer achieves a V oc of 1.24 V

Remarkably MS5 achieves a strikingly high V oc value of 1.24 V, setting a new benchmark for copper-based DSCs. For the given set of components used in this work (dye, oxide, electrolyte), the maximum V oc in a DSC is determined by the difference between quasi-Fermi level of TiO 2, which under intense illumination approaches the energy level of the conduction band edge, and the redox potential
