Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic cell manufacturing equipment technology, specifically to a curing device for solar cells. Background Technology
[0002] Compared to conventional solar cells with a PN junction as their core, back-contact solar cells have no metal electrodes blocking the front side, greatly improving the absorption and utilization rate of sunlight after it shines on the cell surface. This structural design reduces light reflection and shading loss from the front electrodes and grid lines, allowing more sunlight to be absorbed by the cell and converted into electrical energy.
[0003] Despite the numerous advantages of back-contact battery technology, several challenges remain in practical applications. One particularly thorny issue is how to store printed batteries and minimize scratches on the front side. Compared to the traditional method of using paper to protect the front textured surface, insulating adhesive is more convenient and cost-effective. UV-curing adhesive is widely used in photovoltaic BC battery technology, and it requires curing.
[0004] Existing curing devices have fixed light source positions, which limits their applicability. Furthermore, the shrinkage of the curing device during UV curing can easily cause silicon wafer warping, leading to abnormal automated transmission and affecting CT and yield. Utility Model Content
