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 JiaA 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.
