Abstract

The invention relates to a double-sided photoresponse perovskite solar cell and a preparation method thereof. The double-sided photoresponse perovskite solar cell comprises a transparent conductive substrate, a photoanode light absorption layer and a transparent composite counter electrode which are sequentially laminated, wherein the transparent composite counter electrode comprises a transparent conductive macromolecule polymer modified by a quantum dot having multi-exciton characteristic and ultraviolet or visible or infrared light absorption characteristic, and the composite transparent electrode having light response to ultraviolet or visible or infrared light is prepared. The invention also comprises the preparation method of the perovskite solar cell. The low-cost and dual-sided photoresponse perovskite solar cell employs a macromolecule transparent conductive polymer thin film modified by a narrow-band quantum dot as the counter electrode, the light absorption range of the perovskite solar cell is extended to an infrared wave band by design of double-sided photoresponse, meanwhile, the recycle ratio of the device on a visible part can be improved, so that the photoelectric conversion efficiency of the solar cell is improved by over 30%.
