Abstract

An integrated device of solar cell and photocatalysis (p-Si fronted solar cell/ CoSi2/WO3) has been used as photoanode for water splitting. The WO3 had been synthesized by co-electrodeposition of CoW on the p-Si fronted solar cell and followed by the annealing and acid treatment. The XRD and SEM show the amorphous structure for both as-depostion and after treatment samples. After the treatment, XPS and the ellipsometer spectroscopy shows that the CoSi2 and WO3 was formed with the band gap of 1.32 eV and 2.67 eV, respectively. Without additional power, we had demonstrated that the p-Si fronted solar cell/CoSi2/WO3 can achieve ~ 0.046 mA/cm2 photocurrent.
