A High Voltage Dye-sensitized Solar Cell using a Nanoporous NiO Photocathode

Abstract
An np tandem dye-sensitized solar cell (np-DSC) comprising a titanium dioxide (TiO2) anode and a nickel oxide (NiO) cathode prepared as porous nanostructured films by a sol–gel method using a triblock copolymer template (P123, HO(OCH2CH2)20(OCH(CH3)CH2)70(OCH2CH2)20OH))CH2 exhibited a high open circuit voltage (Voc) of 0.92 V that surpassed the long time champion data, ≈0.8 V for conventional DSC.
