通过ANSYS有限元软件对182 mm×182 mm、210 mm×210 mm、210 mm×105 mm、105 mm×210 mm共4种主流尺寸电池金属化后产生的翘曲行为进行非线性结构分析,进一步明晰了晶硅太阳电池翘曲行为影响机理。结果表明：在150 μm电池厚度下,上述4种不同尺寸电池的最大翘曲值分别为1.30、1.69、1.67、0.45 mm。在210 mm×210 mm尺寸下,70、90、110、130、150 μm共5种不同厚度电池的翘曲值分别为8.25、4.96、3.24、2.28、1.69 mm。研究发现,电池的厚度与尺寸、金属栅线的宽度及屈服强度是影响翘曲变形的主要因素。
Abstract
Four main size cell models of 182 mm×182 mm, 210 mm×210 mm, 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.
