Conductive core plate and manufacturing method

Abstract

The invention discloses a conductive core plate and a manufacturing method. The conductive core plate comprises an insulating material layer, a metal conductive circuit layer, a packaging adhesive film layer and a back plate layer in sequence from top to bottom, wherein all the layers are bonded in a low-temperature heating mode; the metal conductive circuit layer and the packaging adhesive film layer are compounded and bonded, and a conductive circuit diagram is arranged on the metal conductive circuit layer; a plurality of small holes are formed in the insulating material layer, and the positions of the holes correspond to the positions of electrode points on the battery piece; the conductive circuit diagram takes set unit patterns as a basis, and the unit patterns are arranged above thebattery piece in an array manner. According to the invention, the conductive core plate adopts a longitudinal cardinal number column 13*12 half-cut battery arrangement mode, and the cardinal number column battery arrangement is achieved; meanwhile, the number of the batteries connected with the diodes is equal, the installation direction of a junction box is parallel to the short edges of the assembly and is the same as the position of a junction box of a conventional assembly, and if the connection mode is a solder strip assembly, the connection mode is hardly achieved, and the equipment transformation cost can be effectively reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of novel MWT solar cell production equipment, in particular to a conductive core board and a manufacturing method. Background technique [0002] Due to its energy-saving and pollution-reducing features, solar photovoltaic modules are used more and more widely. MWT-type back-contact components are more and more widely used due to their advantages of saving silver paste and high reliability. In response to the development of the market trend, the current photovoltaic industry components are developing in the direction of large area and large size, and MWT technology is no exception, and large area and large size components are also constantly being developed. The main direction of large size and large area is to expand the area of ​​cells. The other direction is to achieve high power by expanding the number of cells arranged. This requires innovation in the arrangement of cells. The industry basically expands...

Problems solved by technology

[0003] Conventional photovoltaic modules are mostly 6*10, 6*12, 6*24 even-numbered arrays. In this case, the diodes are easy to wire. Since the market is developing towards large-size modules, 8*10, 8*12, 8* will be designed 24 arrays and other components, but if the actual situation is due to the storage space of the device, it is impossible to experiment with adding 2 rows of batteries

13*12 or 13*10 cell arrays are difficult to realize based on traditional welding technology, or the diode wiring needs to add a longer and thicker insulating layer, and the process and processing become super complicated, which limits the development and implementation of high-efficiency components
