Description

technical field [0001] The invention relates to a packaging structure of a solar cell assembly, in particular to a packaging structure of a perovskite solar cell assembly and a packaging method thereof, belonging to the technical field of solar cell assemblies. Background technique [0002] With the increasingly serious problems of the global ecological environment and energy shortage, solar photovoltaic power generation has attracted widespread attention from all countries. At present, the cell conversion efficiency of industrialized crystalline silicon is stable at about 19% (monocrystalline) and 17-18% (polycrystalline), and there are technical and cost bottlenecks in further improving efficiency. Although some high-efficiency silicon cell technologies have been continuously proposed, the preparation process of these high-efficiency solar cells is complicated, the quality is not easy to control in mass production, and the requirements for equipment are high. Therefore, it...
