210 mm×105 mm and 105 mm×210 mm were established by using Ansys finite element software
and nonlinear structural analysis was carried out on the warping behavior of double-sided crystalline silicon solar cells after metallization. The influence mechanism of warping behavior of crystalline silicon solar cells was further analyzed. The results show that the maximum warpage values of the four different sizes of cells are 1.30
1.69
1.67 and 0.45 mm
respectively
at the thickness of 150 μm cells. Under the size of 210 mm×210 mm
the warpage values of 70
90
110
130 and 150 μm cells with different thicknesses are 8.25
4.96
3.24
2.28 and 1.69 mm
respectively. The thickness and size of the battery
the width of the metal grid line and the yield strength are the main factors affecting the warping deformation.
