Embodiment 3

[0061] Polymer Metal Complex Coating Solution

[0062] Add 30mL of hydrogen peroxide (concentration: 10%) to the Erlenmeyer flask. Next, after adding 0.3 g of molybdenum trioxide powder, the temperature was raised to 80° C. and stirring was continued for 4 hours to dissolve the powder until the solution became a clear molybdenum acid solution. After the solution was cooled down to room temperature, 0.06 g of polymer PSS was added and stirred continuously for 1 hour for chelation. Finally, 0.08 g of surfactant FS-3100 and 10 mL of ethanol were added, and after stirring continuously for 24 hours, the polymer metal complex coating liquid of Example 3 was obtained.

Abstract

The invention relates to a polymer metal complex coating liquid and an organic photovoltaic element. The polymer metal complex coating liquid comprises a precursor of a metal oxide, a polymer compound, a surfactant and a solvent, wherein the polymer compound has a functional group which can be chelated with the precursor of the metal oxide, and a weight ratio of the polymer compound to the precursor of the metal oxide ranges from 0.1 to 3. The polymer metal complex coating liquid provided by the invention has good stability and can be converted into a metal oxide without a high-temperature treatment process after coating. In addition, an organic photovoltaic element prepared from the polymer metal complex coating liquid provided by the invention has better energy conversion efficiency (PCE).
