Embodiment 2

[0069] This embodiment provides a packaging method for photovoltaic modules, refer to image 3 , the method includes:

[0070] Step S1: providing a back plate matching the shape of the battery strings connected in series.

[0071] The shape of the back plate is determined by the shape of the battery string. When the battery string is square, the back plate is a corresponding square shape; when the battery string is circular, the back plate is Corresponding to the circular shape, that is to design a corresponding structure of the back plate according to the shape of the battery string.

[0072] In order to speed up the heat dissipation speed of the photovoltaic module, the backplane adopts a metal backplane, and the metal material has excellent heat dissipation performance, which can quickly dissipate the heat generated by the photovoltaic module during photoelectric conversion, and avoid the solar battery sheet being damaged due to temperature rise. The reduction of photoele...

Description

technical field [0001] The invention relates to the technical field of solar cell manufacturing technology, and more specifically, to a photovoltaic module and a packaging method thereof. Background technique [0002] With the increasingly prominent energy crisis, the development and utilization of new energy has become the main topic of research in the field of energy. Because solar energy has the advantages of no pollution, no regional restrictions, and inexhaustible supply, the study of solar power generation has become the main direction for the development and utilization of new energy. Solar power generation is divided into photothermal power generation and photovoltaic power generation. [0003] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The key components of this technology are solar cells, which can be packaged and protected after being co...
