The photocurrent density of the electrode based on the Bi 2S3/ Bi2OSe heterojunction is increased by 7times and 263 times compared to that of the pure Bi2S3 electrode and the pure BizO2Se electrode,respectively. This is due to the formation of a Van der Waals heterojunction of Bi2S3/B 121 OSeat the interface,which greatly improves the solar absorptionefficiency of the electrode material,improvestspatiocfotogeatedtroeiddusteobatioateoftooleis.
