Abstract
The utility model discloses a wedge-shaped welding rod applied to connection of a crystalline silicon solar cell. The wedge-shaped welding rod comprises a welding rod wedge-shaped section and a welding rod section, both of which are connected together, the welding rod wedge-shaped section and the front surface of the crystalline silicon solar cell piece are in contact and are welded together, the welding rod section and the back surface of the crystalline silicon solar cell piece are in contact and are welded together, the welding rod wedge-shaped section is in a shape of a wedge, and the welding rod section is wedge-shaped or rectangular. The wedge-shaped welding rod disclosed by the utility model has a simple structure and has the advantages of reducing the wire resistance of the welding rod, reducing the shielding area of the front surface of a cell, largely increasing the output power of the cell and reducing the power loss from the cell to an assembly due to the wire resistance of the welding rod, so as to improve the quality of products.
Description
Technical field
The utility model belongs to new energy field, is specifically related to the wedge shape welding rod that a kind of crystal-silicon solar cell connects usefulness.
Background technology
The monolithic crystal-silicon solar cell since its output voltage less than 1 volt, and output current often reaches several amperes, so monolithic battery independent utility scope is very limited.Generally speaking; We are together in series crystal-silicon solar cell through using metal electrode, are packaged into assembly, to improve its output voltage; Make it to reach the application corresponding requirement; Traditional welding rod is shaped as wide strip, and it is different that the shortcoming of this welding rod shape is to reckon without the welding section current density of welding rod, causes the equiva lent impedance of welding rod not to be optimized to minimum value.
Summary of the invention
Goal of the invention: the utility model provides a kind of crystal-silicon solar cell that can reduce the resistance of welding rod line, minimizing battery front side shading area to connect the wedge shape welding rod of usefulness to the deficiency of prior art.
Technical scheme: in order to achieve the above object; The utility model is achieved in that specifically a kind of crystal-silicon solar cell connects the wedge shape welding rod of usefulness, and it includes welding rod wedge-shaped segment and welding rod section, and welding rod wedge-shaped segment and welding rod section link together; The welding rod wedge-shaped segment contacts with the front of crystalline silicon solar cell piece and welds together; The welding rod section contacts with the back side of crystalline silicon solar cell piece and welds together, and the welding rod wedge-shaped segment is a wedge-type shape, and the welding rod section is wedge shape or rectangular shape.
Beneficial effect: the utility model is simple in structure; It is to cooperate solar cell wedge shape master The Grid-Lines Design; Not only can reduce the resistance of welding rod line, and can reduce battery front side shading area, improve the power output of battery greatly; Reduce the power loss that battery causes because of the resistance of welding rod line to assembly, thereby improved the quality of product.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
The embodiment of the utility model as shown in the figure is such:: a kind of crystal-silicon solar cell connects the wedge shape welding rod of usefulness; It includes welding rod wedge-shaped segment 1 and welding rod section 2; Welding rod wedge-shaped segment 1 links together with welding rod section 2, and welding rod wedge-shaped segment 1 contacts with the front of crystalline silicon solar cell piece 31 and welds together, and welding rod section 2 contacts with the back side of crystalline silicon solar cell piece 32 and welds together; Welding rod wedge-shaped segment 1 is a wedge-type shape, and welding rod section 2 is wedge shape or rectangular shape.
