Recently, the team of Professor Han Liyuan of Shanghai Jiaotong University teamed up with Suzhou Liyuan New Energy Technology Co., Ltd. to form an R&D team for production, education, research and development. Using the key technology of independent intellectual property rights, a battery module with an area of ​​36 square centimeters and an energy conversion efficiency of 12.1% was obtained.
This achievement is the world's first certified perovskite battery module record. It is certified by the International Institute of Industrial Technology (AIST), the world's leading certification body, and is the world's highest efficiency perovskite solar cell module. The relevant research results are published in the latest issue of "solar cell efficiency tables" (MA Green et al., Solar cell efficiency tables (version 49)], filling the gaps in research in this field in the world for a long time. This achievement has greatly promoted the research of low-cost solar cells and the process of large-scale industrialization in the future.
Organic metal-halogen perovskite materials have great advantages in the field of optoelectronics because of their advantages such as adjustable band gap, high charge mobility, and simple preparation. Especially in the field of low-cost solar cells, the energy conversion efficiency of organometallic halogen perovskite solar cells has approached that of conventional silicon solar cells, and it is the most promising photovoltaic technology for lower power generation costs than petrochemical energy. According to the team's research, the perovskite solar module's efficiency reached 12% life span of 15 years, perovskite's industrialization cost was 0.07 USD/W, and the cost of power generation can be lower than traditional petrochemical energy. The research of this kind of solar cell has attracted the extensive attention of academia and industry, attracting a large number of science and technology and industrial researchers to turn to this field for fierce competition. At present, whether it can realize large-area high-efficiency perovskite solar modules has become a key issue that restricts the industrialization of perovskite solar cells.
