Problems solved by technology
[0004] However, during the use of this kind of ribbon, we found that because the ribbon needs to be connected to the arrayed multi-cell battery units, one section of the ribbon is zigzag facing the outside, but the other adjacent piece After the battery unit is installed, the serrated surface will be used as the connection surface between the ribbon and the battery. Since the surface of the ribbon is serrated, the contact area with the battery is reduced.

Embodiment Construction
[0044] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0045] In order to achieve the purpose of the present invention, as Figure 2-8 As shown, in some embodiments of the trapezoidal welding ribbon of the present invention, two racks 2 with a trapezoidal cross-section are provided along the length direction of the welding ribbon 1, and the two racks 2 are arranged along the width of the welding ribbon 1 direction, and an angle 21 is formed between the two racks 2 . When the welding ribbon 1 is connected to the battery sheet 4, the rack 2 of one section is set outward, and its back is connected to the front of the battery sheet 4, and the rack 2 of the next section is connected to the back of the battery sheet 4, and so on. , thus forming the photovoltaic module of the present invention.
[0046]In this ribbon and its components, there are two trapezoidal racks on the surface of the ribbon. Alt...

Abstract
The invention discloses a trapezoidal welding strip, wherein at least one rack with trapezoidal section is arranged along the length direction of the welding strip. The invention also discloses a photovoltaic module and a preparation method of the trapezoidal welding strip. As compared with the prior art, the welding strip provided by the invention is endowed with two great advantages of improving power of battery pieces and guaranteeing the connection strength of the welding strip and the battery pieces, meanwhile, the two technical problems are solved simultaneously, performance and application range of the welding strip are expanded effectively, and overall performance and quality of the photovoltaic module are improved.
Description
technical field [0001] The invention relates to a welding ribbon in the field of photovoltaic products, in particular to a trapezoidal welding ribbon, a photovoltaic module and a preparation method thereof. Background technique [0002] In the current photovoltaic modules, the surface of the ribbons used is almost smooth and plane. Such ribbons are good for welding, but they will completely reflect back the sunlight that hits the surface of the ribbons, which reduces the battery life. The utilization rate of sunlight limits the further improvement of module power. [0003] In order to solve the above technical problems, there is now a kind of solder ribbon with a serrated surface, which can effectively reflect the light through the function of the serrated surface, so that the light can be collected on the battery as much as possible, so as to improve the performance of the battery. power. [0004] However, during the use of this kind of ribbon, we found that because the r...
