Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to photovoltaic manufacturing field, concretely relates to a carrier and coating equipment for battery double -sided coating. BACKGROUND
[0002] In the production process of photovoltaic cells, laser slicing is a common step, but during slicing, certain cutting loss often occurs, resulting in damage to the edges of the cells. These damages need to be reduced by passivation treatment to reduce the current leakage of the cells, thereby improving the efficiency and life of the cells.
[0003] The existing half-piece passivation equipment only needs to process the edges after cutting. This method is suitable for half-piece cells because they only need to be passivated on one side. However, with the development of photovoltaic cell technology, more and more cells are cut into multiple pieces, which makes the passivation requirement more complex. Multiple-piece cells need to be passivated on both cutting surfaces.
[0004] For multiple-piece cells, the existing passivation equipment achieves double-sided passivation by changing the size of the magazine. Because the bottom of the existing magazine is a fixed structure, the operation process of this method is to passivate the cell piece once, re-load, place the already passivated side at the bottom of the magazine, and perform the passivation process again. Although this way can complete double-sided passivation, it has some shortcomings. First, the re-loading process increases the complexity of production and is prone to additional loss of broken pieces. Second, this additional process step reduces production efficiency and increases operating and time costs. SUMMARY
