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

A dye-sensitized solar cell (DSSC) fabricated by using a novel silyl-anchor coumarin dye with alkyl-chain substitutes, a Br(3)(−)/Br(−) redox electrolyte solution containing water, and a Mg(2+)-doped anatase-TiO(2) electrode with twofold surface modification by MgO and Al(2)O(3) exhibited an open-ci...

Sumario:A dye-sensitized solar cell (DSSC) fabricated by using a novel silyl-anchor coumarin dye with alkyl-chain substitutes, a Br(3)(−)/Br(−) redox electrolyte solution containing water, and a Mg(2+)-doped anatase-TiO(2) electrode with twofold surface modification by MgO and Al(2)O(3) exhibited an open-circuit photovoltage over 1.4 V, demonstrating the possibility of DSSCs as practical photovoltaic devices.
