The invention discloses a reflecting film material for a photovoltaic assembly. The reflecting film material is prepared by the following steps: step one, adding polyethylene glycol terephthalate and polysilazane into a low-molecular solvent and stirring the mixed solution for 2 to 4 hours; step two, adding a coupling reagent, an initiator, and a catalyst into the mixed solvent, carrying out sealing and shielding-gas pressurized reaction for 2 to 5 hours, thereby obtaining a reaction solution; step three, adding a metallic packing material, organic titanium salt, and a dispersing agent into the reaction solution and stirring the mixed solution uniformly, and then carrying out high-temperature methane backflow aeration reaction for 3 to 6 hours; step four, after natural cooling, carrying out low-temperature aging on the processed reaction solution for 5 to 8 hours; step five, adding carbene into the processed reaction solution, carrying out low-temperature stirring, and then carrying out aeration dispersion re
