Amplifying the Performance and Stability of Perovskite Solar Cells Using Fluorinated Salt as the Surface Passivator
First published: 06 January 2023
Graphical Abstract
A simple passivation strategy using a common fluorinated salt is reported that seeks to enhance the photovoltaic performance and long-term stability of halide perovskite solar cells. Tetra-n-butyl ammonium hexa-fluorophosphate is used as a passivating agent to mitigate the surface defects on the perovskite and impede the ion mobility by virtue of H-bonding. In addition, the presence of fluorine atoms causes strong hydrophobicity, which in turn improves the moisture stability in perovskite solar cells. More details can be found in article number 2200211, Samrana Kazim and co-workers.
