2023 Perovskite Technology, Equipment and Materials Forum

• Meeting background

  Perovskite cells are a promising next-generation photovoltaic power generation technology with low temperature coefficient, high upper limit of efficiency, and great potential for cost reduction. Universities and scientific research institutions around the world and China are actively investing in the research and development of perovskite technology. In April 2023, a laboratory efficiency of 26% for single-junction perovskite cells has been achieved.

• 
• 2023 is the first year of the industrialization of perovskite batteries. Leading perovskite companies such as Jidian, GCL, Xinan, Yaoneng, and Renshuo are promoting mass production; traditional photovoltaic giants such as Longji, Tongwei, Trina, Huasheng, and Jolywood are actively investing in research and development; in addition, Ningde Times, Huaneng, CNNC, Toyota, Mingyang Intelligent and other industry giants are also making continuous progress in the perovskite field.

• The all-perovskite laminated battery, and the laminated battery composed of crystalline silicon and perovskite, are expected to achieve a substantial increase in efficiency. In June 2023, LONGi announced that it has achieved a conversion efficiency of 33.5% for crystalline silicon-perovskite stacked cells on commercial-grade textured CZ silicon wafers. With the sharp drop in the price of polysilicon, the investment proportion of modules in photovoltaic power plants has decreased, creating good conditions for the commercial application of high-efficiency stacked cells.

  
  

  The rapid development of the perovskite and tandem battery industry has brought huge market opportunities for technology, equipment and material suppliers. The technical route of perovskite can be divided into dry method and wet method, each with its own advantages. The challenges faced by perovskite technology are mainly the further improvement of commercial-scale battery efficiency, large-scale manufacturing and long-term stability, as well as the improvement of relevant testing standards and testing technologies.

• The 2023 Perovskite Technology, Equipment and Materials Forum will be held in Changzhou on September 11-12. The meeting will discuss the outlook of the photovoltaic industry and the market prospect of perovskite and tandem batteries, the latest progress in global and Chinese perovskite academic, scientific research and industrialization, the laboratory preparation and industrial production process, equipment and materials of perovskite photovoltaic devices, calcium The cost reduction path of titanium battery and the selection of key equipment, the conversion efficiency, stability and test standards of perovskite and laminated batteries, the packaging technology and packaging materials for perovskite and laminated batteries, etc.
