Embodiment 1

[0022] The preparation process of the polymer solar cell containing the hole transport layer involved in the present invention is as follows (all operations are completed under nitrogen protection):

[0023] (1) Substrate pretreatment: Divide the ITO conductive glass to a size of 15mm*15mm, use detergent, deionized water, acetone, and ethanol to sonicate three times, each time for 30 minutes, then use deionized water to sonicate the substrate for 30 minutes, and rinse completely ;Finally blow dry completely with nitrogen for use;

[0024] (2) Preparation of the hole transport layer: 55 parts by weight of polyvinyl carbazole, 22 parts by weight of tricresyl phosphate and 20 parts by weight of isoviolanthrone were mixed uniformly in 300 parts by weight of toluene solution to obtain the hole-filling layer. Organic components, adding a filler component composed of 45 parts by weight of polynitrogen sulfide, 30 parts by weight of coking polyacrylonitrile fibers and 22 parts by weig...

Embodiment 2

[0027] The preparation of the hole transport layer in step (2) of Example 1 is adjusted as follows: 50 parts by weight of polyvinylcarbazole, 20 parts by weight of tricresyl phosphate and 18 parts by weight of isoviolanthrone are mixed in 300 parts by weight of toluene solution Uniform, to obtain the organic component of the hole-filling layer, to which is added a particle size smaller than The 5nm filler component was mixed evenly by ultrasonic to obtain the stock solution of the hole transport layer, and then the stock solution of the hole transport layer was spin-coated on the ITO glass substrate with a thickness of about 70nm, and then dried at 120°C for use.

[0028] That is, only the content of the components in the hole transport layer was adjusted, and the rest of the preparation process was the same as in Example 1.

Abstract

The invention relates to hole transmission material used for a polymer solar cell. The hole transmission material comprises organic components and packing components. The organic components include polyvinyl carbazole, tricresyl phosphate and isoviolanthrone. The packing components include sulfide nitrogen polymers, coking polyacrylonitrile fibers and silicon ring ferrocene polymers. According tothe hole transmission material, the prepared hole transmission layer can adjust the energy level matching of the anode and the photosensitive active layer, transmit hole block electrons, adjust the electrode surface energy, increase the interface stability, enhance the cell life and further enhance the open circuit voltage, the short circuit current and the photoelectric conversion efficiency of the cell so that the comprehensive performance of the cell can be effectively enhanced and the preparation process is simple and has the prospect of mass production.

Description

technical field [0001] The invention belongs to the field of solar cells, and in particular relates to a hole transport material for polymer solar cells. Background technique [0002] At present, commercial solar cells are mainly prepared from silicon materials or other inorganic semiconductors, but the supply of silicon raw materials is tight and the production cost is high, so there is no significant advantage in the competition with other conventional cells, while organic solar cells have low The advantages of cost, portability, flexibility, etc., have more prospects for large-scale production and use. In recent years, organic solar cells have developed rapidly. Among them, polymer solar cells, as a new type of organic thin-film solar cells, have a maximum efficiency of more than 10%. There is still a certain gap, but there is still a lot of room for improvement in terms of materials and device structural performance. [0003] The working principle of polymer solar cells...
