Embodiment 1
[0028] Mix 100 parts of epoxy tung oil with 2 parts of cationic photoinitiator bis(4-p-tolyl) iodonium hexafluorophosphate; apply the mixture on the light-receiving front of the solar cell, then cover it with a glass plate, and Remove the air bubbles in the interlayer; then irradiate the tung oil coating with a medium-pressure mercury lamp with a power of 800W for 4 minutes, and the lamp distance is 20cm. Packaging process. The tung oil-based adhesive layer of the finished product is not thicker than 0.5mm and is colorless.
Embodiment 2
[0030] Mix 90 parts of epoxy tung oil with 10 parts of Daicel alicyclic epoxy resin CELLOXIDE 2021P (trade name of Daicel Chemical Industry Co., Ltd. in Japan), 1.5 parts of cationic photoinitiator bis(4-p-tolyl) iodine hexafluorophosphate The onium salt is mixed evenly; the mixture is evenly coated on the light-receiving front of the solar cell, then covered with a glass plate, and the interlayer air bubbles are removed; then the tung oil coating is irradiated with a medium-pressure mercury lamp with a power of 800W for 3 minutes, and the lamp distance is 20cm , the coating is quickly cured by light, and the solar cell is firmly bonded to the glass plate, and the packaging process of the light-receiving surface is completed. The tung oil-based bonding layer of the finished product is not thicker than 0.5mm and is colorless.
Embodiment 3
[0032] Mix 90 parts of epoxy tung oil with 10 parts of Daicel alicyclic epoxy resin CELLOXIDE 2021P (trade name of Daicel Chemical Industry Co., Ltd. in Japan), 1.5 parts of cationic photoinitiator bis(4-p-tolyl) iodine hexafluorophosphate Onium salt, 0.5 parts of fluorescent powder, 0.5 parts of UV absorber 2-hydroxy-4-n-octyloxybenzophenone were mixed evenly; the mixture was uniformly coated on the light-receiving front of the solar cell, then covered with a glass plate, and removed Bubbles in the interlayer; then irradiate the tung oil coating with a medium-pressure mercury lamp with a power of 800W for 3 minutes, and the lamp distance is 20cm, the coating is quickly cured by light, and the solar cell is firmly bonded to the glass plate to complete the packaging of the light-receiving surface process. The tung oil-based bonding layer of the finished product is not thicker than 0.5mm and is colorless.
