Abstract
This paper conducts a comprehensive cross-sectional study on poor PV module junction boxes with solidified bubbles,and identifies three types of bubbles and their generation mechanisms.By adjusting the physical properties of the potting compound and designing control experiments,a method to completely solve the potting bubbles was found.The experimental results show that the viscosity of the potting adhesive can be effectively reduced,the leveling performance can be improved,and the frequency of bubbles after filling the miniaturized junction box can be effectively reduced by prolonging the stirring time,increasing the stirring speed and heating treatment of the filler.In terms of improving the leveling of potting compound,increasing the mixing speed can increase the leveling by 5.4%,extending the mixing time can increase by 10.1%,and preheating superposition can increase the mixing speed and extending the mixing time by 15.5%.关键词
