The invention provides a light conversion adhesive film as well as a preparation method and application thereof. The light conversion adhesive film comprises a base film, and fluorescent carbon dots capable of performing light conversion are adsorbed on the surface of the base film; the fluorescent carbon dots capable of performing light conversion are adsorbed on the surface of the base film, so that the light conversion adhesive film can absorb ultraviolet light and convert the ultraviolet light into visible light capable of being utilized by a solar cell, the light conversion adhesive film is further applied to a solar photovoltaic module as a packaging adhesive film, and the photoelectric conversion efficiency of the solar photovoltaic module can be effectively improved; meanwhile, the preparation method of the light conversion adhesive film is simple, preparation can be completed at room temperature, complex operation conditions such as high temperature are not needed, the structure of the fluorescent ca
