As an important part of the photovoltaic industry,photovoltaic glass technology is constantly innovating.The thickness of the glass gradually decreases to 2.0 mm,and it is developing in the direction of ultra-thinness.The decrease in the thickness of the glass leads to an increase in difficulty during the annealing control process and increased defects.Through discussing the problems in the annealing process and the corresponding solutions,three main directions of the annealing temperature system control are put forward.Stabilizing the annealing process of thin glass will help reduce the loss of the annealing and increase the product yield.
