A photoelectron chemical solar cell was formed by Pt/graphene/SiNW, in which the electrolyte is 0.5M KNO3, 0.1M K3Fe(CN)6, and 0.1M K4Fe(CN)6, and the other electrode is FTO glass. The photoelectron conversion efficiency of the solar cell is 0.3% under 1.5AM condition, which is higher than 0.17% of the solar cell formed by SiNW, and higher than 0.074% of the solar cell formed by Si. A scanning electron microscope, a Raman spectrometer, and an energy dispersive spectrometer were used for the morphology and composition analysis.
