Enhanced Optical Path and Electron Diffusion Length Enable High-Efficiency Perovskite Tandems

Published in Nature Communications 2020, 11 (1), 1257, 2020

A boosted solvent extraction method increases perovskite film thickness while preserving smooth morphology, and a Lewis base additive extends the electron diffusion length to 2.3 μm, enabling 19% semi-transparent top cells and 28.2% perovskite/silicon tandem solar cells.
