Abstract

The invention relates to the field of photovoltaics, in particular to a slotted battery piece and a battery piece module. The slotted battery piece comprises a battery piece body, a main grid line isarranged on the front surface of the battery piece body, and a groove is formed at the position, close to the end of the main grid line, on the battery piece body. A first welding layer is laid on themain grid line, a second welding layer corresponding to the first welding layer in position is laid at the back surface of the battery piece body, and the front and rear ends of the first welding layer and the front and rear ends of the second welding layer respectively form a front welding end and a rear welding end. The battery piece module comprises a plurality of slotted battery pieces, and the second welding layer on the previous slotted battery piece is connected with the first welding layer on the current slotted battery piece through a bending welding strip; and the bending welding strip penetrates the groove. The slotted battery piece and the battery piece module can improve module efficiency, reduce the risk of battery piece breakage and reduce single piece cost.

Description

technical field [0001] The invention relates to the field of photovoltaics, in particular to a slotted cell and a cell assembly. Background technique [0002] At present, due to the limitation of more slivers in the production process of photovoltaic modules, it is necessary to design a larger spacing between cells. The distance between traditional cells is mostly 2.0 to 3.0 mm. This structure reduces the efficiency of the module, reduces the power of the module per unit area, and increases the cost per watt. [0003] The invention designs a grid line slotted battery technology. A battery of the structure is used. Can greatly shorten the distance between the cells. The shortest cell spacing can be reduced to 0.1 mm. It is dozens of times shorter than before. This technology can improve module efficiency. Reduce the risk of cell splitting. At the same time, the cost per watt can be reduced. Contents of the invention [0004] In order to solve the deficiencies in the...
