Zhan Xiaowei's group and collaborators from the School of Materials Science and Engineering, Peking University designed a novel fullerene derivative FP-C8 to replace the classic material PCBM as the electron transport layer for trans-perovskite solar cells
Perovskite solar cells are simple to prepare and low cost, and their photoelectric conversion efficiency is comparable to that of crystalline silicon cells, which has attracted widespread attention worldwide
To replace the classic electron transport material PCBM in trans-perovskite solar cells, we designed a novel fullerene derivative, FP-C8, which consists of a C60 carbon cage, a long alkyl chain, and a terpyridine end group
JV curves of perovskite solar cells based on PCBM and FP-C8 electron transport layer and schematic diagram of the interaction between PCBM and FP-C8 and perovskite surface
Jiang Yiting, a doctoral student in Zhan Xiaowei's research group, is the first author of the paper, and Tu Yingfeng of Soochow University, Zhou Huanping and Zhan Xiaowei of Peking University are co-corresponding authors
This work was funded by the National Key R&D Program of the Ministry of Science and Technology and the National Natural Science Foundation of China
