According to the invention, the perovskite solar cell can be effectively packaged, and the stability of the packaged device is obviously improved, and meanwhile, the metal lead in contact with the perovskite solar cell electrode can facilitate the actual test and connection of the device.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic cell manufacturing, and relates to a simple perovskite solar cell packaging structure and a manufacturing method thereof. Background technique [0002] Due to the advantages of high energy conversion efficiency and low manufacturing cost, perovskite solar cells have received continuous attention from academia and industry in recent years. However, the stability problem of perovskite materials is one of the biggest obstacles on the road to its commercial application. Common high-efficiency perovskite materials will decompose due to moisture and oxygen in the air when they are in contact with air. Therefore, perovskite should strictly avoid contact with outside air in future practical applications. Effective encapsulation of the battery is particularly important. [0003] In perovskite solar cells with commonly used structures, in addition to perovskite materials, the functional layers and me...
