Fabrication of a dye-sensitized solar cell containing a Mg-doped TiO 2 electrode and a Br 3 − /Br − redox mediator with a high open-circuit photovoltage of 1.21 V

A dye-sensitized solar cell (DSSC) fabricated by using a Mg(2+)-doped anatase-TiO(2) electrode with an alkoxysilyl dye and a Br(3)(-)/Br(-) electrolyte solution exhibited successfully a remarkably high open-circuit photovoltage over 1.2 V, demonstrating a new possibility of DSSCs as practical photovoltaic devices.
