The invention relates to a method for preparing a perylene polyimide derivative film in the technical field of photoelectric materials. In the method, hydrazine hydrate is used for replacing trifluoroacetic acid, a positive electrode deposition method is adopted, and a dense and uniform film is prepared with a low voltage of 0.5-5V and a low current of 0.02-5mA within a relatively short deposition time. Moreover, composite films conforming to various absorption ranges are prepared through changing the structure and the matching of the perylene polyimide derivative.

The invention discloses selenium-substituted benzodipyrene imide and synthesis method as well as application to a solar battery. The synthesis method is characterized in that: perylenetetracarboxydianhydride is taken as a raw material for preparing anhydride perylene bisimide dimer anhydride through butyl tetracarboxy perylene; different alkyl chain-substituted and selenium-substituted benzodipyrene imide can be prepared easily and simply through an anhydride intermediate. The acceptor molecule has superior photoelectric property, can be applied to organic solar battery, and has simple requirement on device structure, and the photoelectric conversion efficiency under the condition of no optimizing manners such as solvent additive, thermal annealing and the like can reach up to 5.17 percent.
