The Steady-state Efficiency Of Perovskite Batteries Reaches 26.7%!

On July 3rd, the internationally authoritative solar cell world record list "Solar cell efficiency tables" (Version 64) released the world record for the performance of perovskite batteries led by Professor Xu Jixian's team at the University of Science and Technology of China, with a certified steady-state efficiency performance of 26.7%.

This is the third time that the team has continuously updated the world record list on behalf of the University of Science and Technology of China since 2022 (Version 60) and 2023 (Version 63). In 2023, the team achieved a dual breakthrough in the efficiency of perovskite batteries, surpassing 26% and breaking the world record for traditional formal device monopolies, with a certified efficiency of 26.1% for trans devices. This achievement is another leading breakthrough in the continuous and arduous research on this basis, which has a positive promoting effect on the construction of stacked batteries.

The Solar Cell Efficiency Tables are reviewed and published by the Australian Advanced Photovoltaic Center in collaboration with scientists from multiple countries including the United States, Japan, Italy, and Australia. It has a history of nearly 30 years and is recognized by the international photovoltaic academic and industrial fields for its objectivity and honor. It represents the latest technological developments in various sub sectors of photovoltaics and has important guiding significance. This inclusion represents the breakthrough and leading ability of China University of Science and Technology in the forefront of photovoltaic research and development.

This study is the latest achievement of Professor Xu Jixian's team in the field of new perovskite single junction and next-generation crystalline silicon perovskite stacked batteries, which has a promoting effect on industrialization.
