The invention discloses a solar cell and a packaging method thereof. The solar cell comprises a first thermosetting sealing film, and a substrate layer, a solar chip and a second thermosetting sealingfilm which are sequentially arranged on the first thermosetting sealing film, the periphery of the first thermosetting sealing film and / or the periphery of the second thermosetting sealing film protrude / protrudes out of the periphery of the substrate layer and the periphery of the solar chip, the periphery of the first thermosetting sealing film and the periphery of the second thermosetting sealing film are overlapped, and the first thermosetting sealing film and the second thermosetting sealing film are connected through hot pressing to package the substrate layer and the solar chip. The packaging method of the solar cell comprises the following steps: sequentially laying a substrate layer, a solar chip and a second thermosetting sealing film on a first thermosetting sealing film to forma laminated structure, and hot-pressing the laminated structure to connect the first thermosetting sealing film and the second thermosetting sealing film so as to package the substrate layer and thesolar chip. According to the packaging method of the solar cell, the packaging process is simple and convenient, the energy consumption is relatively low, and the packaging efficiency is relatively high.
Description
technical field [0001] The invention relates to the technical field of solar energy, in particular to a solar cell and a packaging method for the solar cell. Background technique [0002] Existing flexible thin-film solar cells are usually processed by vacuum hot-press packaging process. The vacuum hot-press packaging process mainly includes the following steps: laying flexible substrate, solar cell chip, waterproof film layer and outer protective film sequentially from the bottom layer to the top layer , There is also a hot-melt adhesive film layer between each layer, and then it is packaged by vacuum lamination process, and then the finished product is obtained by autoclave process. This process mainly uses waterproof film material to package the solar cell chip, and then uses a transparent polymer outer protective film such as PET film to protect the battery. Glue the layers together. However, the interlayer structure of solar cells using the vacuum hot-pressing packagi...
