Achievement of over 1.4?V photovoltage in a dye-sensitized solar cell by the application of a silyl-anchor coumarin dye.

ABSTRACT: A dye-sensitized solar cell (DSSC) fabricated by using a novel silyl-anchor coumarin dye with alkyl-chain substitutes, a Br3(-)/Br(-) redox electrolyte solution containing water, and a Mg(2+)-doped anatase-TiO2 electrode with twofold surface modification by MgO and Al2O3 exhibited an open-circuit photovoltage over 1.4?V, demonstrating the possibility of DSSCs as practical photovoltaic devices.
