Abstract

The invention discloses a flexible series-parallel imbricated photovoltaic module and a manufacturing method thereof, and belongs to the technical field of photovoltaic power generation. The photovoltaic module comprises a front plate, a front adhesive film, an imbricated battery piece group, a rear adhesive film and a back plate, wherein the imbricated battery piece group is packaged between thefront plate and the back plate, the front adhesive film is arranged between the front plate and the imbricated battery piece group, the back adhesive film is arranged between the imbricated battery piece group and the back plate, the front surface and the back surface of each battery piece in the imbricated battery piece group are respectively provided with an electrode, and the front plate and the back plate are flexible plates. The front plate and the rear plate are made of flexible materials, and the conductive adhesive is a silicon-based conductive silver adhesive; after being packaged, the conductive adhesive has excellent elasticity after being cured; the series-parallel imbricated photovoltaic module has the advantages that the partial stress of the series-parallel battery pieces isreduced, the problem of subfissure of the battery pieces can be well solved, the foundation settlement resistance is high, the combination with a building is good, the high-power advantage of the series-parallel imbricated photovoltaic module can be exerted in various occasions, and the application range of the series-parallel imbricated photovoltaic module is expanded.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a flexible series-parallel shingled photovoltaic module and a manufacturing method thereof. Background technique [0002] The series-parallel shingled photovoltaic module not only connects the battery slices in series, but also realizes the parallel connection of the battery slices by means of staggered connection, which completely eliminates the need for welding strips, and has the advantages of high power and strong resistance to local shading. However, series-parallel shingled photovoltaic modules will cause greater stress to local cell slices due to a large number of continuous interlaced and overlapping cell slices, and are more likely to cause cracks when combined with flexible technology than traditional modules. In addition, conventional series-parallel shingled photovoltaic modules use toughened glass like traditional photovoltaic module...

AI Technical Summary

Problems solved by technology

However, series-parallel shingled photovoltaic modules, due to a large number of continuous interlaced and overlapping cell slices, will cause greater stress to the local cell slices, and when combined with flexible technology, they are more likely to cause cracks than traditional components.

In addition, conventional series-parallel shingled photovoltaic modules use toughened glass like traditional photovoltaic modules, resulting in their poor resistance to foundation settlement and poor integration with buildings, which limits the scope of use of shingled modules and cannot be used in more Take advantage of its high power in many occasions
