Solar panel and manufacturing method thereof

Abstract

The invention relates to the technical field of photovoltaic solar cells, in particular to a solar panel and a manufacturing method thereof. The solar panel comprises a glass substrate, a cell unit and a protective film layer covering the cell unit, wherein the edge and the bottom face of the solar panel are provided with sealing protective layers used for sealing the connection face between the bottom face of the solar panel and the protective film layer and the connection face between the bottom face of the solar panel and the glass substrate, and the sealing protective layer comprises a frame and a bottom face layer and is made of plastic. Sealing protective films are formed on the edge and the bottom of glass in an injection molding mode and are used for covering the edge of the glass and organic sealants, and accordingly moisture is prevented from entering the solar panel, waterproof and sealing performance of the solar panel which is used for a long time outdoors is improved, the service life of the solar panel is prolonged, and the solar panel is firmer and more durable.

[0002] With the increasing shortage of energy, the development and utilization of renewable energy has attracted more and more attention, especially the utilization of solar energy. As a solar energy conversion medium, solar panels are the core part of solar power generation systems. The function is to convert the radiation ability of solar energy into electric energy, and then send the electric energy to the storage battery for storage, or push the load to work. The common crystalline silicon solar panel includes a glass substrate, and there are usually battery cells on the surface of the glass substrate, which includes Use low-pressure chemical vapor deposition or normal-pressure chemical vapor deposition to deposit tin oxide, zinc oxide, and other transparent conductive oxide films on glass substrates, and use plasma-enhanced chemical vapor deposition to deposit photoelectric conversion layers on the surface of TCO. Silicon-based solar energy is widely used in outdoor occasions to provide power for various street lamps, garden lamps and outdoor solar products. These solar panels need to withstand the test of natural environments such as wind and rain all year round. Over time, the protective film The layer is prone to aging, and the moisture in the external environment slowly penetrates into the interior of the battery board, causing damage to the internal battery cells
