Abstract
In this paper, mechanical properties and PET crystallinity of PV backsheet after damp heat ageing,accelerated damp heat ageing and UV irradiation ageing were studied. Relationship between failure of backsheet and crystallinity of PET layer was concluded. The different ageing patterns above were compared. The results show that, in precess of damp heat ageing and accelerated damp heat ageing, PET layer go crystallizing, and crystallinity should be controlled under 38% for backsheet without failure. In precess of UV irradiation ageing, Molecular structure of PET was destroyed. By comparing the mechanical properties, we found that UV irradiation ageing gave greater influence to PET layer of PV backsheet.关键词
