Technical Field

[0002] Photovoltaic modules are devices that convert solar energy into electrical energy. They are generally composed of high-efficiency single-crystal or polycrystalline solar cells, protective components, packaging materials, backplanes and frames. They use the photovoltaic effect of semiconductor materials to directly convert solar radiation energy into electrical energy without emitting pollutants. They are a clean, safe and renewable energy source with a wide range of applications.

[0003] Existing photovoltaic modules have the following disadvantages during use: Existing photovoltaic modules are generally single-sided crystalline silicon cell structures and use tempered glass as a protective panel. In actual use, in order to ensure light transmittance and avoid the influence of factors such as hot spot effect, there are strict restrictions on the thickness of the tempered glass. Although it has a good light transmittance effect, in actual use, especially when used in some severe weather environments, it is often affected by snow accumulation, sandstorms, typhoons, etc., and the glass panel will often break or even affect the photovoltaic panel, resulting in high maintenance costs. For this reason, we propose a double-sided solar crystalline silicon cell module. Utility Model Content
