Embodiment 1

[0028] The structure of the organic solar cell device in this embodiment is ITO / anode interface / active layer / PFN-Br / Al, and the preparation steps are as follows:

[0029] After the ITO was repeatedly ultrasonically washed with acetone, ITO cleaning solution, deionized water, and isopropanol, it was dried in an oven at 80°C at a constant temperature. The ITO was then transferred into a nitrogen-protected glove box, and the conductive polymer was electrochemically polymerized using cyclic voltammetry in a three-electrode electrolytic cell system.

[0030] The specific steps of electrochemical polymerization of conductive polymers by cyclic voltammetry are as follows: EDOT is dissolved in 0.1M tetrabutylammonium hexafluorophosphate electrolyte solution, so that the concentration of EDOT is 0.1M, and cyclic voltammetry is used at 0-1.0V Scan in the range of 200mV / s, scan 5 circles, wash and dry for the anode interface of organic solar cells.

Abstract

The invention discloses a preparation method and application of an anode dipole interface of an organic solar battery. The preparation method comprises the following steps: using cyclic voltammetry to apply a voltage of 0 to 0.4 to 1.8V to a conductive polymer monomer electrolyte solution of 0.01M to 0.1M, using a scan rate of 50mV / s to 600mV / s, and polymerizing 2-10 laps, deposit on the ITO electrode to obtain a conductive polymer film; spin-coat an oxidant solution with a concentration of 0-5 mg / ml on the electrochemically polymerized conductive polymer film to obtain a dipole interface. The invention can regulate the thickness and roughness of the film when preparing the conductive polymer film, can be prepared in a large area, and does not need steps such as annealing. By spin-coating the oxidant solution, the conductivity, roughness, work function, hydrophobicity, mobility and other properties of the interface can be adjusted to improve the performance of organic solar cells.
