Problems solved by technology
[0003] In the prior art, when the double-glass module is used, because the double-glass module is installed outdoors, the temperature difference between day and night is relatively large in cold winter, and the double-glass module is due to thermal expansion and contraction, which causes the loosening of the cells and reduces the double-glass module. In addition, in winter, ice will form on the double-glass components, which will damage the double-glass components and reduce the service life of the double-glass components

The invention discloses a novel double-sided battery double-glass assembly. The double-glass assembly comprises a double-glass assembly body, the double-glass assembly body further comprises two pieces of transparent glass, two packaging adhesive films EVA2 and solar cell assemblies, and the solar cell assemblies are pasted to the adjacent faces of the two packaging adhesive films EVA2. An electric heating wire, a fixing plate and a heat conduction layer are arranged, the fixing plate is heated through the electric heating wire, heat can be transferred to the heat conduction layer, the heat conduction layer transfers the heat to the packaging adhesive film EVA2 and the solar cell assemblies, the whole double-glass assembly can maintain a balanced temperature, the temperature difference of the double-glass assembly is reduced, in cold winter, the situation that due to the fact that the temperature difference between day and night is large, the double-glass assembly expands with heat and contracts with cold, and the battery pieces are loosened is avoided, the service life of the double-glass assembly is prolonged, meanwhile, the double-glass assembly can be prevented from being frozen, the double-glass assembly is prevented from being damaged, and the service life of the double-glass assembly is further prolonged.
Description
technical field [0001] The invention relates to the technical field of double-glass components, in particular to a novel double-glass component of a double-sided cell. Background technique [0002] The two sides of the double-glass module of the new double-sided cell can be used at the same time, thereby effectively improving the power generation efficiency. Among the traditional solar cells, the single-crystal silicon cell has the highest light conversion efficiency, which can reach about 19%. This new type of double-sided solar cell The light conversion efficiency can be further increased to 20%-30%. At the same time, the power generation efficiency of the single-chip battery has also increased from 4W-4.5W of the traditional battery to 4.5W-6W. In the case of increasingly intensified contradictions between resource supply and demand, the further development and utilization of solar energy will definitely become a future development trend, and this product has opened up a...
