Embodiment Construction

[0018] The technical solutions of the present invention are described in detail below in conjunction with the examples. The present invention discloses a multi-grid high-efficiency photovoltaic module, which combines Figure 1-Figure 2 As shown, it includes several battery strings 1, the battery strings 1 are formed by several battery slices, the battery strings 1 are connected by a new type of reflective ribbon 2, and at least 13-20 main grids are arranged on the battery slices, so The diameter of the main grid is 0.2mm-0.3mm.

[0019] Since the operation is more difficult when more than 16 busbars are welded, the diameter of the welding wire used is smaller, and the research and development cost is higher. Preferably, there are 16 main grid lines, because the 16 main grid lines can reduce the distance that the current passes through the fine grids, and can also reduce the current carried by each main grid, so the resistance loss rate is smaller and the conversion efficiency ...

Abstract

The invention provides a multi-grid and high-efficiency photovoltaic module. The multi-grid and high-efficiency photovoltaic module comprises a plurality of battery strings, wherein the battery strings are formed from a plurality of battery pieces, the battery strings are connected by welding strips, at least 13-20 main grids are arranged on the battery pieces, and the welding strips are reflective welding strips. The multi-grid and high-efficiency photovoltaic module has the beneficial effects that the current collection efficiency of the battery pieces can be obviously improved by the multi-grid photovoltaic module, the distance of a current passing through a fine grid is reduced, and a current borne by each main grid is reduced; and meanwhile, the product cost is also reduced, and the multi-grid and high-efficiency photovoltaic module has bright prospect in future development.

Description

technical field [0001] The invention belongs to the field of solar photovoltaic components, and in particular relates to a multi-grid high-efficiency photovoltaic component. Background technique [0002] At present, the country pays more and more attention to new energy, and the photovoltaic field is one of the best. With the continuous increase of competitiveness, the power of batteries has become an issue that researchers pay more and more attention to under the premise of ensuring low cost. The number of busbars of existing solar cell modules is generally three to four. When it reaches more than five, the traditional solar cell module manufacturing technology will be unsustainable, and a new metallization scheme is needed to realize multi-busbar solar energy. Industrialization of cell components. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the invention provides a multi-grid high-efficiency photovoltaic module. [0004] The ...
