Copper Bipyridyl Redox Mediators for Dye-Sensitized Solar Cells with High Photovoltage

Shaik Mohammed Zakeeruddin, Jacques-Edouard Moser, Nikolaos Vlachopoulos, Ulf Anders Hagfeldt, Ladislav Kavan, Fabrizio Giordano, Norman Pellet, Yiming Cao, Yasemin Saygili, Marina Freitag

Redox mediators play a major role determining the photocurrent and the photovoltage in dye-sensitized solar cells (DSCs). To maintain the photocurrent, the reduction of oxidized dye by the redox mediator should be significantly faster than the electron bac ...
