Abstract:

As the third generation of new concept solar cells, perovskite solar cells have the advantages of high photoelectric conversion efficiency, low-cost and flexible processing. They have been developed rapidly in recent years. Their photoelectric conversion efficiency has increased from 3.8% at the beginning to 25.5% in the near future. They are gradually comparable to silicon cells and have been close to the level of commercial application. At present, the key link to realize the industrial application of perovskite solar cells is battery packaging. It can not only solve the stability problem of perovskite photovoltaic devices, but also meet the requirements of battery safety, environmental protection and prolonging service life. Combined with the development status of perovskite photovoltaic cell packaging materials and packaging technology in recent ten years, this paper introduces the achievements and shortcomings in the field of perovskite cell packaging, and discusses the advantages and disadvantages of the existing packaging technologies, as well as their applicable different device types. Under different temperature and humidity conditions, the effects of different packaging material properties and packaging process conditions on the efficiency and stability of perovskite battery are compared, and three key factors affecting the packaging effect of perovskite battery thin film are summarized: elastic modulus of polymer, water vapor transmittance and processing temperature. The suitable processing temperature, advantages and disadvantages and processing cost of different polymer film packaging materials are compared. It can be seen that with the strong growth of industrial demand for perovskite photovoltaic cells and the deepening of people's research on their packaging materials, it will be an inevitable trend to study new functional polymer packaging materials suitable for large-scale production and photovoltaic building integration.

Key words: Perovskite solar cell, Encapsulation, Stability, Photovoltaic building integration
