Problems solved by technology

[0004] Taking the package of traditional crystalline silicon battery components as an example, hot melt adhesives such as EVA\POE\PVB are often used for high-temperature (140°C-150°C) lamination packaging, but there are obvious differences between the production process of perovskite and crystalline silicon. Mine has relatively poor water resistance and high temperature resistance. It is necessary to develop packaging materials with near "zero" water permeability and a process with a maximum packaging temperature of no more than 100°C that are feasible and popular for mass production in order to meet various reliability indicators. Relevant processes cannot be directly applied to perovskite. New processes must be redeveloped and matching materials and equipment must be selected. There are improvements in existing technologies

Embodiment 1

[0044] In step 3, the sealant layer 4 adopts a lamination process, including a lamination device arranged outside the isolation box 2, and the lamination device presses a low-temperature curing hot-melt adhesive on the battery pack 1 on completion of step 2.

[0045] The existing lamination process uses the principle of water to transmit pressure evenly. By pressurizing the water in the sealed container, a high-pressure system is formed, and the pressure is evenly applied to the battery pack 1 placed in the water, so that the structure is dense and the surface is smooth. ;Using the lamination process to melt the low-temperature curing hot-melt adhesive and press it on the UV adhesive layer 3, which overcomes the technical difficulty of packaging the perovskite battery pack 1 using a laminator, and greatly reduces the packaging cost of the perovskite battery pack 1. equipment requirements and technical requirements.

[0046] Further, the low temperature curing hot melt adhesive...

Embodiment 2

[0048] Step 3 is carried out outside the isolation box 2, and the liquid glue film is coated on the battery pack 1 after step 2 by using a coating roll coating process or a coating roll pressing process, and the sealant layer 4 is formed after the liquid gel solidifies.

[0049] The coating process is to use a coating machine to evenly coat the uniform slurry produced by the pulping process on the substrate 11 according to certain density and thickness requirements, and to remove the organic solvent or moisture in the slurry after baking. .

[0050] The coating process is more suitable for the production of perovskite thin-film batteries. Whether it is a rigid substrate 11 or a flexible substrate 11, the coating process can be used to form a sealant layer 4 on the UV adhesive layer 3 that is bonded to the battery pack 1. The coating process requires less equipment investment than the lamination process, and can continue to operate in a pipeline, which greatly improves the pack...

Abstract

The invention discloses a packaging method of a perovskite thin film battery pack. Based on perovskite thin film battery production, the method comprises the following steps: S1, the method involves abattery pack and an isolation box for containing the battery pack, the battery pack comprises a base material and a hole layer, the hole layer is coated with a UV adhesive layer in a water-proof andoxygen-proof environment of the isolation box, and the UV adhesive layer covers the hole layer of the whole battery pack; S2, the UV adhesive layer coating the hole layer is irradiated and cured; andS3, the battery pack subjected to the step S2 is taken out from the isolation box, and a sealant layer is arranged on the cured UV adhesive layer. The UV adhesive layer coats the hole layer, the UV adhesive layer can be fixed through light irradiation, the UV adhesive layer is cured without generating heat and moisture, and a compact UV adhesive layer can be formed after curing on the perovskite battery pack. Therefore, the battery pack is isolated from oxygen and water, the subsequent arrangement of the sealant layer is facilitated, and the investment cost and requirements for creating and meeting the production environment of the perovskite battery pack are reduced.

Description

technical field [0001] The invention relates to the technical field of packaging of perovskite battery packs, in particular to a packaging method for perovskite thin film battery packs. Background technique [0002] In recent years, due to the improvement of environmental awareness worldwide, the supply and demand for green energy has gradually become stronger. Under this background, the development and industrialization of the photovoltaic industry are advancing with each passing day. Among many forms of photovoltaic cells, thin-film solar cells have attracted many companies to develop, invest and advance because of their lightness and mass production characteristics. Among them, the perovskite battery with the most competitiveness and development potential has become a star material for new energy materials because of its high photoelectric conversion efficiency, low cost, and simple process steps. [0003] However, perovskite materials are sensitive to temperature and hu...
