Embodiment Construction

[0027] 1) Substrate processing

[0028] Put the ITO conductive glass into a beaker, ultrasonically clean it with acetone, absolute ethanol, and deionized water for 20 minutes, and dry it with nitrogen after cleaning;

[0029] 2) Preparation of self-assembled polyfluorene transport layer

[0030] a, ITO surface hydroxylation treatment

[0031] The ITO substrate was soaked in a pre-prepared 1mg / mL methanol solution of KOH for 20h, and it was subjected to hydroxylation treatment, so that a layer of OH was suspended on the surface of the ITO.

[0032] b, Self-assembly interface preparation

[0033] Polyfluorene PDHF-Cl is dissolved in tetrahydrofuran solvent and prepared as a solvent of 1000PPM for use, and then the obtained PDHF-Cl solvent is spin-coated on the surface of hydroxylated ITO by spin coating, and the spin-coating speed is 1000rpm; The ITO conductive glass with PDHF-Cl is annealed at 100°C for 20 minutes; during the annealing process, the Cl in the PDHF-Cl molecule...

Abstract

The invention belongs to the technical field of polymer solar cells, and particularly relates to an organic solar cell based on the polyfluorene cathode interface self-assembly anode plasma resonance effect and a preparation method of the organic solar cell. According to the method, an amphipathic polyfluorene material with high conductivity serves a cathode transmission layer, interface contact with ITO is increased through self-assembly of the cathode transmission layer, the cathode transmission layer replaces a traditional TiO2 or ZnO inorganic transmission layer, interface combination is reduced, and the performance of the organic solar cell is improved; meanwhile, a vacuum evaporation method is adopted for directly arranging a layer of gold nanoparticles on an active layer in an evaporation mode, light scattering is increased by utilizing the surface plasma effect of the layer of gold nanoparticles, the light path is increased, then the light utilization rate is increased, and thus the performance of a device is improved. The efficiency of the organic solar cell is effectively improved through the method, and the method is of great reference significance for nanoimprint lithography and development of organic solar cells in the future.

Description

technical field [0001] The invention belongs to the technical field of organic solar cells, and in particular relates to an organic solar cell based on polyfluorene cathode interface self-assembled anode plasma resonance effect and a preparation method thereof. Background technique [0002] Organic solar cells have attracted more and more attention from researchers in recent years because of their unique advantages such as flexibility, bendability, low cost, and large-area printing production. It has been reported in the literature that inversion organic solar cells based on blend systems have high efficiency. However, for the inverted polymer organic solar cells based on inorganic oxides as the cathode transport layer, the inherent defects of the inorganic oxides and the shortcomings of the sol condensation method make the prepared cells have high carrier recombination and low excitation. Solving the shortcomings caused by the inorganic transport layer and further improving...
