摘要

为利用热机械分析优化光伏组件寿命,在建立具有精细结构热力学模型的基础上,考虑中间膜材料在低温情况下的玻璃化转变,并加入焊锡黏塑性模型,以研究在高空温度冷热循环过程中,组件各材料因热膨胀系数不匹配导致的热机械应力,比较乙烯-醋酸乙烯酯共聚物（EVA）、聚烯烃弹性体（POE）、聚乙烯醇缩丁醛（PVB）作为中间膜时焊点疲劳寿命的区别,发现POE作为封装材料时焊点的疲劳寿命更长。

Abstract

In order to optimize the lifespan of solar cell modules through thermal mechanical analysis, this paper establishes a thermal-mechanical model with fine structure, considering the glass transition of the intermediate film material at low temperatures and the tin solder plastic model. On this basis, this study investigates the thermal-mechanical stress caused by the mismatch in thermal expansion coefficients of the materials during the high-altitude environmental thermal cycling process. The study also compares the differences in tin solder joint fatigue life when using Ethylene-Vinyl Acetate（EVA）、Polyolefin Elastomer（POE） and Polyvinyl Butyral（PVB） as intermediate films. The results show that when POE is used as encapsulation material, the solder joint will have a longer fatigue life.
