摘要：

An integrated solar water splitting tandem cell without external bias was designed using a FeOOH modified TiO2/BiVO4 photoanode as a photoanode and p-Cu2O as a photo-cathode in this study. An apparent photocurrent (0.37 mA/cm(2) at operating voltage of +0.36 V-RHE) for the tandem cell without applied bias was measured, which is corresponding to a photoconversion efficiency of 0.46%. Besides, the photocurrent of FeOOH modified TiO2/BiVO4 Cu2O is much higher than the operating point given by pure BiVO4 and Cu2O photocathode (-0.07 mA/cm(2) at +0.42 VRHE). Then we established a FeOOH modified TiO...
