title: 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 Mg2+-doped anatase-TiO2electrode with twofold surface modification by MgO and Al2O3exhibited an open-circuit photovoltage over 1.4 V, demonstrating the possibility of DSSCs as practical photovoltaic devices.
