An interconnection structure of a solar wing cell assembly and its preparation process

Abstract

The invention discloses an interconnection structure of a solar wing cell assembly and a preparation process thereof. The interconnection structure includes more than one pair of positive and negative lead-out wires provided in a single battery assembly, and adopts flat conductor lead-out wires. The lead-out points of the lead-out wire pairs interconnected by adjacent battery assemblies are arranged close to the assembly interface and are arranged opposite to each other. On both sides of the junction surface, the interconnected lead-out pairs are drawn out from the back of the battery module along the same side direction, and are routed closely to the back of the battery module in an overlapping position and finally connected, and the adjacent battery modules are connected to the wing rib Location. The preparation process includes the preparation of the lead wire and the lead wire structure, the battery assembly installation, the lead wire interconnection pair overlap connection and the lead wire insulation protection. Compared with the traditional interconnection structure, the interconnection structure greatly simplifies the interconnection structure, reduces the weight of the interconnection structure, reduces the battery cell spacing area between components, and improves the utilization rate of the laying area of ​​the solar cells.

Description

technical field [0001] The invention belongs to the technical field of solar cell preparation, and in particular relates to an interconnection structure of a solar wing cell assembly and a preparation process thereof. Background technique [0002] As a clean and renewable energy source, solar cells have been greatly commercialized worldwide. [0003] Among them, conventional crystalline silicon solar cells have certain advantages in terms of process maturity, cost, efficiency, reliability, etc., and occupy a considerable market share in the solar cell market. Conventional crystalline silicon solar cell modules are generally rigid components, which are products obtained by laminating or encapsulating tempered glass, conventional crystalline silicon cells, adhesives, and transparent films. They are more suitable for large buildings such as solar power stations and roofs. use. [0004] Compared with conventional rigid solar cells, flexible solar cells have the characteristics...

Problems solved by technology

At the same time, for the laying and installation of flexible components on the wing frame, the edge of the component needs to be installed on the solid structure of the wing frame such as the wing rib and the front and rear edges. Usually, it needs to be installed on both sides of the rib and the rib edge, resulting in a large gap between the components along the direction of the wing span, which is not conducive to the further improvement of the utilization rate of the laying area

At the same time, interconnection structures such as junction boxes, cables, and docking plugs are heavy, and the cables need to go around through the rib structure to connect with adjacent components. At the same time, a fixed structure needs to be added to prevent it from shaking. The structure is complex and increases. Useless weight is reduced, which is not conducive to the further reduction and simplification of solar wing weight
