Synergistic modulation of interfacial energy levels and defect passivation via a fluorinated PTAA interlayer for efficient perovskite solar cells

Zhongquan Wan, Haibin Zhao, Yunpeng Zhang, Shuhao Deng, Muhammad Azam, Junsheng Luo, Chunyang Jia

A fluorinated PTAA interlayer is designed to address the interfacial energy-level mismatch and non-radiative recombination between the perovskite and hole-transport layer in PSCs, boosting the PCE from 22.41% to 24.78% with improved stability.
