Strengthening Durability of Electron Selective Layer and Interface via Trifluoromethoxy-Functionalized Biguanide Cation Toward High-performance Air-Processed n-i-p Perovskite Solar Cells
{{output}}
The poor stability of the electron-selective layer (ESL) and buried interface hampers the realization of long-term operationally stable air-processed n-i-p perovskite solar cells (PSCs). Herein, ESL and the buried interface are stabilized through a trifluorome... ...
