The Institute of Chemistry has developed n-type photovoltaic materials with high efficiency, low cost and high stability

In recent years, thanks to the development of non-fullerene acceptors, major breakthroughs have been made in the photoelectric conversion efficiency of organic solar cells

With the support of the National Natural Science Foundation of China, the Ministry of Science and Technology and the Chinese Academy of Sciences, Zhu Xiaozhang's research group, a researcher at the Key Laboratory of Organic Solids, Institute of Chemistry, Chinese Academy of Sciences, has carried out in-depth research on n-type photovoltaic materials and devices, and has developed a series of high-tech Performance photovoltaic acceptor materials, and constructed a series of high-performance photovoltaic devices

Based on the accumulation in the design, synthesis and device application of n-type photovoltaic materials, and inspired by the successful design of high-mobility fused-ring organic semiconductors, the research group proposed the "fully fused-ring electron acceptor (AFAR)" in 2021.

Recently, they developed a new fully fused ring electron acceptor material (F-acceptor) to achieve near-infrared responsiveness by introducing a benzothiadiazole-based core skeleton

This work provides a paradigm for collaboratively addressing cost, efficiency, and stability challenges in organic solar cells, and the related results were published in CCS.
