Simulation of pyrolysis physical field and temperature optimization of the encapsulating materials of decommissioned Cu(InGa)Se2 photovoltaic laminated module
The composition and formation behavior of each component of decommissioned Cu(InGa)Se2 module encapsulating materials at different pyrolysis temperature under nitrogen atmo-sphere 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.Simula-tion 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.
