Description

technical field [0001] The invention belongs to the field of photovoltaic power generation technology and photovoltaic building integration, and in particular relates to a photovoltaic module based on a perovskite solar cell and a packaging method thereof. Background technique [0002] At present, the industrialization technology of crystalline silicon solar cells is very mature. However, compared with traditional energy sources, the higher cost of power generation restricts the large-scale popularization of crystalline silicon solar cells. In recent years, perovskite solar cells have developed rapidly, and their advantages are very prominent: 1. Organic-inorganic hybrid perovskite materials are easy to manufacture and low in cost; 2. They have a relatively suitable bandgap width (1.5-2.3eV), The range of light absorption is large; 3. The charge diffusion length is up to micron level, and the charge life is long. 4. Flexible and transparent batteries can be prepared. There...
