摘　　要：采用Atlas UV2000紫外老化测试仪,对不同组成的EVA胶膜进行了长达1000h的紫外光老化试验。分析了不同组成的EVA胶膜老化过程中力学性能、透过率和黄色指数的变化,以及老化前后太阳电池组件外观及Ⅰ-Ⅴ特性的变化。研究表明,选择合理复配的含抗氧剂、紫外光稳定剂和紫外光吸收剂的抗老化体系,所制备的EVA胶膜B-17和B-28具有优异的耐紫外光老化的性能,能满足太阳电池封装需要。EVA films made from different components have been aged by ultraviolet for 1000 hours in testing apparatus, Atlas UV2000. On the base of experimental results, the performances change of different kinds of EVA films in processing of ultraviolet aging, which include mechanics performance, transparence, yellow index, appearance and W-curve of solar modules encapsulated by those EVA films were analyzed. The research results indicated that the prepared EVA film B-17 and B-28, which comprise appropriate antioxidant, ultraviolet absorbefacient and stabilizing reagent possessing excellent resistance to ultraviolet aging. The EVA films are able to be used for solar cells.
