Simulation of pyrolysis physical field and temperature optimization of the encapsulating materials of decommissioned Cu(InGa)Se_(2)photovoltaic laminated module

在氮气氛围下,研究了不同热解温度时退役Cu(InGa)Se_(2)光伏层压件封装材料的气态产物组成及各组分的生成行为。以节能降碳为控温依据,选取467℃为目标热解温度,并以438 oC和497℃为对照温度,进行建模分析和模型验证。通过热-流复合物理场模拟,优化调整后的实际目标、对照热解温度为490、465和525℃。可以发现,将目标热解温度467℃调整至490℃后可将平均温度误差由57.18℃减小至5.76℃,下降约89.93%。在490、465和525℃温度下,当热解温度进入200℃以上的高温区间时,平均误差分别仅为3.62、4.72和3.29℃。这表明所建立的模型在高温区间内具有良好的准确性和指示作用。

The composition and formation behavior of each component of decommissioned Cu(InGa)Se_(2)module encapsulating materials at different pyrolysis temperature under nitrogen atmosphere were studied.In order to save energy and reduce carbon emissions,467℃was selected as the target pyrolysis temperature,while 438℃and 497℃were chosen as the control temperature.Simulation of thermal-flow compound physical field and model verification were conducted.And the actual target pyrolysis temperature and control temperature were adjusted to 490,465 and 525℃.It was found that when temperature was adjusted from 467 to 490℃,the average temperature error of pyrolysis can be reduced from 57.18℃to 5.76℃,which was reduced by 89.93%.At the temperature of 490,465 and 525℃,when the temperature is above 200℃,the average errors were only 3.62,4.72 and 3.29℃.It shows that the model has good accuracy and indicating effect in high temperature range.
