A high voltage dye-sensitized solar cell using a nanoporous NiO photocathode
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(OCH2-CH20(OCH(CH3)CH2)(70)(OCH2CH2)(20)OH))CH2 exhibited a high open circuit voltage (V-oc) of 0.92 V that surpassed the long time champion data, approximate to 0.8 V for conventional DSC.
