摘要： Systems and methods for manufacturing solar panels are disclosed. Solar cells are placed on a conveyor that transports the cells from a start point to an end point. A laser scribing module scribes the cells at a predetermined depth. A paste dispensing module deposits a predetermined amount of conductive paste on the surface of the solar cells. A cleaving apparatus divides the cells into smaller strips. A shingling module creates a string of cells by overlapping the strips. A targeted annealing module cures the paste, and a layup module places the strings on a backsheet. A glass cover is then added to one side of the strings.
