太阳能电池片导电胶串焊技术及电池片受力分析

String-welding Technology of Conductive Film of Solar Cells Type and Force Analysis of Solar Type

随着太阳能电池片厚度的减薄及市场无铅低温焊接的需求,促使导电胶新型自动串焊技术成为一种趋势,与普通串焊技术相比,主要增加了贴胶、胶带预压及胶带终压三步工序,减少了助焊剂喷涂一步工序。在终压工况下,针对主背栅偏移的数值不同,建立电池片的ANSYS有限元模型,进行应力状态分析。

With the thickness of solar cells type becomes thinner, and the need of lead-free and low-temperature welding, some new type automatic welding become a trend such as the CF equipment. Compared with the conventional welding equip-ment, the stick glue, lamination and final bonding are increased, which reduce the flux spraying and welding parts. In the condition of final bonding,aiming at the difference of main and back busbar offset values, the cell model is established by AN-SYS in order to analyze the stress.
