Solar cell encapsulation sheet and solar cell module

Abstract

The invention discloses a solar battery packaging sheet. The solar battery packaging sheet comprises a packaging bottom plate, a first series battery stack, a second series battery stack and magnets, wherein the first series battery stack and the second series battery stack are independently packaged on the packaging bottom plate; the positive electrode of the first series battery stack and the negative electrode of the second series battery stack are positioned on the identical side of the packaging sheet; the magnets are respectively embedded to the two sides of the packaging sheet; the edges of the magnets are positioned at the outer parts of the edges of the packaging sheet; the output electrodes of the first series battery stack and the second series battery stack are respectively connected with the magnets beside the series battery stacks according to different requirements. The invention further provides another three solar battery packaging sheets and solar battery components comprising the solar battery packaging sheets. The packaging sheets and the battery components provided by the invention can meet different requirements on power of users, and are small in size, convenient to carry and low in cost.

Description

technical field [0001] The invention belongs to the technical field of photovoltaics, and in particular relates to a solar battery packaging thin plate and a solar battery module. Background technique [0002] As the world's energy consumption becomes more and more serious, solar energy, as a pollution-free clean energy, has become the focus of research by scientists from all over the world. In the production process of solar cell modules, the encapsulation of solar cells is a key step. After encapsulation, the strength of the photovoltaic module can be effectively increased, thereby prolonging the service life of the solar cell and the photovoltaic module. Portable photovoltaic modules can greatly improve the efficiency of photovoltaic products. At the same time, as the requirements for installation specifications and product miniaturization are getting higher and higher, the market application prospects of portable photovoltaic modules are very broad. [0003] Most of th...

Problems solved by technology

There is a risk of breaking the connecting wire at the fold; this risk of breaking increases as the solar panel is used

As long as there is one damage to the solar panel or its connecting wires (such as a broken battery or a broken wire), the entire portable solar panel will fail;

[0004] In addition, the folding connection of existing products requires a larger volume of solar panels to meet the additional installation space required for connecting devices. Therefore, the area and thickness of existing solar panels are relatively large, which is different from the current miniaturization of photovoltaic modules. contrary to the trend

[0005] In addition, the above-mentioned solar panels are mostly one-piece structures. Under the condition of constant light intensity, the output power is constant, especially the opening voltage and battery cannot be changed, which is not flexible enough and cannot meet the various needs of users.
