AI Technical Summary
The problem of holes and cracks caused by glass warping during the high-temperature vacuum lamination process of photovoltaic modules cannot be effectively avoided.
An elongated concave groove is set at the edge of the battery cell, and the solder strip on the front of the battery cell is electrically connected to the busbar through the concave groove to form a buffer structure to prevent the solder strip from pulling the battery cell during the glass warping process.
This effectively avoids cell cracking caused by glass warping during the lamination process, reducing the defect rate in photovoltaic module production.
