[0001] Cross-reference to related applications

[0002] This application claims the benefit of 4 Chinese patent applications filed on April 8, 2024, with application numbers 202410417065.X, 202410417063.0, 202410417068.3, and 202410417066.4, the contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] The present application relates to the field of solar cell encapsulant, in particular to an organic compound and application thereof, an encapsulant composition, and a method for preparing an encapsulant. BACKGROUND

[0004] Perovskite solar cells have the advantages of simple process, low cost, and high efficiency, and are increasingly attracting attention, and the commercialization speed is gradually accelerating. Since perovskite solar cells are very sensitive to water and oxygen in the environment, they are easily eroded by water and oxygen in the environment, thereby causing the aging of perovskite solar cells and affecting their service life. An effective method to prevent water and oxygen from eroding perovskite solar cells is to use appropriate methods for encapsulation.

[0005] Traditional cover plate encapsulation is to bond the glass substrate with a glass or metal cover plate using an epoxy resin ultraviolet curing adhesive in an inert gas-filled glove box or vacuum environment, thereby sealing the organic layer and electrode and isolating water and oxygen; but the glass cover plate has poor toughness, and the metal cover plate is not transparent, which limits its application in device encapsulation.

[0006] Epoxy resin systems are widely used due to their excellent flexibility, good light transmission performance, and good water and oxygen barrier ability, but epoxy resin encapsulation materials have poor performance such as slow curing speed, insufficient toughness, brittleness, and low heat resistance, and more importantly, perovskite solar cells have a large efficiency decay under ultraviolet light, which will become a major obstacle to the commercialization of perovskite solar cells.

[0007] Therefore, it is necessary to develop an organic encapsulation film with strong water and oxygen barrier ability, high light transmission, high curing rate, and high heat resistance. SUMMARY

[0008] The purpose of the present application is to develop a new organic compound so that when the organic compound is applied to encapsulant, the encapsulant formed thereby can have the advantages of strong water and oxygen barrier ability, high light transmission, high curing rate, and high heat resistance.

[0009] To achieve the above object, a first aspect of the present application provides an organic compound having a benzotriazole structure, the organic compound having a structure represented by formula (I):

Compared with traditional EVA and POE encapsulant films, the encapsulant not only achieves the purpose of blocking water and oxygen, but also solves the damage to the battery caused by ultraviolet light, improves the power generation efficiency of the battery, and has obvious encapsulation effect, simple process and low cost.

[0175] Preparation of encapsulating film

[0176] The preparation process of the examples and comparative examples is the same, except that the amount and specific type of each component are shown in Table 1. Specifically:

[0177] 5 parts by weight of component A, 50 parts by weight of component B, 40 parts by weight of component C, and 5 parts by weight of component D were fed into a 125 ml brown polypropylene bottle, and mixed at room temperature for about 3 hours using a mixer to prepare an encapsulating composition.

[0178] The composition was slit-coated on a glass substrate and cured by UV irradiation at 200 mW / cm2for 180 seconds to form an encapsulating film having a thickness of 10 μm. 2

[0179] The amount and specific type of each component in this example are shown in Table 1.

[0180] The structure in the comparative example is as follows:

[0181] ​Test Example: The products obtained in the foregoing examples were subjected to the following performance evaluations, and the results are shown in Tables 1 and 2. Performance Evaluations:

[0182] 1. Water vapor transmission rate: Using a water vapor transmission rate tester (PERMATRAN-W3 / 33, manufactured by MOCON), the prepared packaging film was subjected to 100% relative humidity at 40°C for 24 hours, and the water vapor transmission rate was measured.

[0183] 2. Photocuring rate: Using FT-IR (Nicolet iS10, by Thermo), it was used to measure the absorption peak intensity of the prepared packaging film at 1635 cm -1 (C=C) and 1720 cm -1 (C=O). The photocuring rate was calculated by Formula 1:

[0184] Formula 1: Photocuring rate (%) = |1-(A / B)| x 100.

[0185] wherein A is the ratio of the absorption peak intensity near 1635 cm -1 to the absorption peak intensity near 1720 cm -1 , and B is the ratio of the absorption peak intensity near 1635 cm -1 to the absorption peak intensity near 1720 cm -1 .

[0186] 3. Light transmittance: Using a UV-visible spectrophotometer (PerkinElmer LAMBDA 950), the prepared packaging film was measured for light transmittance in the visible light range.

[0187] 4. Heat resistance: Using a simple air-blast constant temperature oven, after heating to a constant temperature and time, the heat resistance of the film was evaluated in terms of the physical properties of the film or the surface changes (refer to GB / T, 1735-89 <Paint film heat resistance test method>). Two identical packaging films were used, one sample was heated to 100°C using an air-blast constant temperature oven for 1 h, and then cooled to 25°C, and compared with the standard version left beforehand to check for discoloration, peeling, wrinkling, etc.
