A low-cost and stable perovskite solar battery and a driven photoelectric catalytic device belong to the technical field of solar cells and the technical field of photoelectric catalysis. The device structure mainly includes a low-temperature carbon electrode mesoporous perovskite solar cell, a photoelectrocatalytic electrode, a counter electrode, a photoelectric reaction cell, and a stirring system. The mesoporous perovskite solar cell using low-temperature carbon paste as the positive electrode provides voltage, promotes the electron-hole separation of the photoelectrocatalytic electrode, enhances the photocatalytic effect, and rapidly degrades organic matter in water. The device and method are simple, excellent and stable in performance, and low in cost. The whole system uses solar energy as the only energy source, which is economical, energy-saving, and environmentally friendly. |
