Hexagonal battery piece assembly

Abstract

The invention relates to a photovoltaic cell packaging technique, and aims at providing a hexagonal battery piece assembly. The hexagonal battery piece assembly comprises a piece of front glass and aback plate which are respectively bonded with a battery piece module through a front adhesive film and a back adhesive film, the battery piece module is composed of hexagonal battery pieces, interconnection bars and bus bars with a uniform specification; gaps are reserved among the multiple battery pieces, the multiple battery pieces are arranged in order of parallel adjacent sides of the batterypieces sequentially, and the interconnection bars are in tandem connection to be battery strings; the adjacent battery strings are parallel and staggeredly arranged, an empty area in an included anglebetween the adjacent battery pieces in the same battery string is filled with protruding angles of the battery pieces in the adjacent battery strings, so that the whole layout of the battery pieces is in a honeycomb structure form; the interconnection bars of each battery string are connected to a junction box through the bus bars. The hexagonal battery piece assembly can improve the output powerof the assembly, and reduces the cost of the assembly. A staggered arrangement mode is used, compared with a traditional side-by-side type arrangement, the empty area is reduced, the effective powergenerating area can be increased, and the front shading area of the battery pieces can be reduced.

Description

technical field [0001] The invention relates to photovoltaic battery packaging technology, in particular to a component packaging of hexagonal battery slices. Background technique [0002] With the increasingly fierce competition in the photovoltaic module market, the lean production of all aspects of photovoltaic is becoming more and more important. The cost of silicon wafers accounts for about 30% of the cost of all raw materials. At present, when silicon rods (cylindrical) are cut into mainstream silicon wafers (approximately square), more waste will be generated. In order to reduce the waste of silicon rods, the silicon wafer can be changed from a nearly square shape to a hexagonal shape, and the area of ​​a single silicon wafer can be increased by about 17.2%. If hexagonal cells are used according to the traditional cell layout method and traditional module size, the amount of cells will be less and more areas of useless work will be generated. Therefore, in order to ...
