Anion optimization for bifunctional surface passivation in perovskite solar cells

Nature Materials, Published online: 30 October 2023; doi:10.1038/s41563-023-01705-y

Pseudo-halide anion engineering is an effective surface passivation strategy for perovskite-based optoelectronics but the large chemical space of molecules limits its potential. Here, the authors create a machine learning workflow to find optimized pseudo-halide anions, which are verified in devices with improved performances.Nature Materials, Published online: 30 October 2023; doi:10.1038/s41563-023-01705-yPseudo-halide anion engineering is an effective surface passivation strategy for perovskite-based optoelectronics but the large chemical space of molecules limits its potential.
