TL;DR: A monolithic perovskite/silicon tandem with a certified power conversion efficiency of 29.15% is reported, made possible by a self-assembled, methyl-substituted carbazole monolayer as the hole-selective layer in the perovSKite cell.
Journal ArticleDOI
Visualization and suppression of interfacial recombination for high-efficiency large-area pin perovskite solar cells
Martin Stolterfoht,Christian M. Wolff,José A. Márquez,Shanshan Zhang,Shanshan Zhang,Charles J. Hages,Daniel Rothhardt,Steve Albrecht,Paul L. Burn,Paul Meredith,Thomas Unold,Dieter Neher +11 more
TL;DR: In this article, a planar pin-type perovskite solar cells with undoped organic charge transport layers with photoluminescence imaging was used to visualize all non-radiative recombination pathways.
Journal ArticleDOI
The impact of energy alignment and interfacial recombination on the internal and external open-circuit voltage of perovskite solar cells
