Abstract

A dye-sensitized solar cell (DSSC) fabricated by using a Mg²⁺-doped anatase-TiO₂ electrode with an alkoxysilyl dye and a Br₃⁻/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.
