Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic materials, and in particular to a polymer color light conversion material, a color light conversion adhesive film and a photovoltaic module. Background Art

[0002] With the continuous advancement of solar cell technology, the photoelectric conversion efficiency of solar cells has gradually increased. For example, the commonly used N-type TOPCon and heterojunction solar cells (HJT) replace PERC solar cells, and there are new thin-film solar cells, such as perovskite solar cells and organic solar cells. However, high-energy light in sunlight, that is, ultraviolet light, will have an impact on solar cells. This is mainly manifested in that when solar cells are exposed to ultraviolet light for a long time outdoors, the photoelectric conversion efficiency of the cells will decrease, and the component materials will be damaged to a certain extent; but simply shielding the ultraviolet light will lose part of the energy of the sunlight. Therefore, the development of a color light conversion material that can absorb ultraviolet light and convert it into low-energy light so that it can be used by solar cells has become an urgent problem to be solved by photovoltaic plants, film plants, and component plants. In response to the above problems, color light converters came into being. This is a color light conversion material that can convert ultraviolet light into visible light.

[0003] So far, many types of color conversion agents have been developed and applied in the photovoltaic field, such as inorganic rare earths, zinc sulfide quantum dots, carbon dots, etc. There is also a type of color conversion agent composed of organic small molecules, most of which appear in conjugated structures. However, both inorganic and organic small molecule color conversion agents have large molecular polarity forces, which cause these molecules to aggregate with each other and then migrate from the inside of the membrane to the surface of the membrane through van der Waals forces, thus affecting the service life of the membrane.

[0004] Therefore, in order to solve the above technical problems, it is urgent to develop a new type of polymer color light conversion agent material. Summary of the invention

[0005] Due to the above-mentioned defects in the prior art, the present invention provides a new type of polymer-type color light conversion agent material, specifically a polymer-type color light conversion material, whose structural unit is based on a biphenyl structure, which has the advantages of simple structure, low development cost and high luminous efficiency. The present invention introduces this structure into the color light conversion agent to obtain a color light conversion agent that is not easy to aggregate, not easy to migrate out and has a high fluorescence quantum yield, and a durable light conversion adhesive film, which overcomes the defects of existing inorganic color light conversion agents and organic small molecule color light conversion agents that have large molecular polarity forces, causing these molecules to aggregate with each other and then migrate from the inside of the film to the surface of the film through van der Waals forces, thereby affecting the service life of the film.

[0052] (3) The intermediate product (54.6 g) obtained in step (2) was added to a reactor and deoxygenated by nitrogen. Then, anhydrous tetrahydrofuran (THF, 300 mL) was injected into the reaction vessel under a nitrogen atmosphere. The reaction temperature was lowered to -78°C. Then, n-butyl lithium (2M, 120 ml) was slowly added to the reaction vessel. After half an hour of reaction, isopropyl borate (39.1 g) was added at the same temperature. The reaction was continued for one hour. After the reaction was completed, after the temperature rose to room temperature, deionized water (200 ml) was added to quench the reaction. Then, 300 ml of ethyl acetate was added to extract the reaction solution three times to obtain an organic phase. The organic phase was concentrated by vacuum distillation. Finally, the concentrate was recrystallized with methanol to obtain 9,9-dioctyl-2,7-diboronate fluorene (yield 93%).
