研究目的
To determine the glass transition temperature, peak melting point, degree of crystallinity, Vinyl Acetate content, and thermal stability of Ethylene Vinyl Acetate (EVA) Copolymer encapsulant for PV module lamination.
研究成果
DSC and TGA analysis successfully determined the thermal properties and VA content of EVA. The degree of crystallinity was found to be similar for uncured and cured EVA, with a high degree of crosslinking achieved after curing. EVA was found to be thermally stable up to 285.13°C, with an initial VA content of approximately 29%.
研究不足
The study focuses on the thermal properties and VA content of EVA, but does not address other potential degradation mechanisms or the long-term outdoor performance of PV modules.
