Abstract

The invention relates to a polymer photoelectron film, a preparation method and application thereof. The polymer photoelectron film includes a polymer film loaded on a substrate, wherein a layer of conductive modified film is arranged between the substrate and the polymer film; the substrate includes glass covered by tin indium oxide (ITO), glass covered by fluoro indium oxide, glass covered by semitransparent silver film and glass covered by semitransparent gold film; the loaded polymer film includes Poly (3-hexylthiophene), PCBM and MEH-PPV; and the conductive modified film is PEDOT: sodium polystyrene sulphonate. The preparation method includes the steps of cleaning the substrate, modifying the substrate, loading the polymer film on the modified substrate, and controlling the volatilization time and the annealing heat treatment of dissolvent in the polymer film. The invention has the advantages that the performance of the prepared polymer photoelectron film is obviously higher than that of polymer film prepared under normal pressure, the performances of the solar cells and other semiconductor devices can be greatly improved, and the market competitiveness can be strengthened; and the invention has low cost and simple operation, and can be easily combined with the traditional semiconductor production process.

Description
