The invention discloses a conjugated polymer-doped composite functional film, a preparation method and application thereof, and belongs to the field of perovskite battery components. Ternary composite functional films prepared by adding solid electrolytes to conjugated polymers, in which the conjugated polymers mainly play the functions of film formation and hole transport; inert polymers are used to adjust the solution of the composite functional film precursor solution Characteristic, the solid electrolyte improves the hole transport ability in the composite film by doping. The composite functional film prepared by the invention has high conductivity and is easy to transport holes, the performance of the functional layer film can be regulated by adjusting the composition ratio of the film, the preparation process is simple and feasible, and the cost is low. The perovskite cell prepared based on this has high charge collection efficiency and low charge loss at the electrode interface, and thus has high photoelectric conversion efficiency. |
