IT Home June 8th news, according to China Science Daily, recently, Professor Peng Jun and Zhang Xiaohong from Suzhou University jointly with the University of New South Wales and Baimahu Laboratory in Zhejiang Province, have made major breakthroughs in the research and development of single-junction perovskite solar cells. The single-junction perovskite solar cells developed by the team have achieved significant improvements in efficiency in different areas, with the certified steady-state efficiency of 0.1 square centimeter batteries reaching 27.3%, and the certified steady-state efficiency of 1 square centimeter batteries reaching 26.9%, both of which set the world record in this area and simultaneously topped the internationally authoritative "Solar Cell Efficiency Table" (66th Edition).
According to IT Home, the team has made many key technical breakthroughs in the field of single junction perovskite solar cells. In February 2025, the team increased the certified steady-state efficiency of small-area single-junction perovskite solar cells to 27% for the first time, and the result was successfully listed on the "Maximum Solar Cell Research Efficiency Map" released by the National Renewable Energy Laboratory of the United States.
The Solar Cell Efficiency Table (66th Edition) specifically points out that during the area expansion, the loss of battery efficiency is extremely small, which is in sharp contrast to previous research results. This breakthrough progress marks the team's successful conquering of the "area-efficiency" contradiction and provides a practical solution for the industrial application of perovskite photovoltaic technology.
