Vacuum-assisted thermal annealing for stable, efficient perovskite photovoltaics
Eliminating a chemical byproduct from perovskite films by vacuum-assisted thermal annealing enables fabrication of highly stable and efficient solar cells.

A novel experimental approach is used to measure spectral correlations between photoexcitations and thus investigate the generation of photocarriers in excitonic solar cells.
