Dion-Jacobson Phase 2D Layered Perovskites for Solar Cells with Ultrahigh Stability

(Joule 3, 794–806; March 20, 2019) In the originally published version of this article, Figure 6A was incorrectly duplicated as Figure 6D. The figure has been updated online and in print to include the corrected Figure 6D. The authors regret this error.Figure 6.

The hydrogen bonding formed at both sides of diammonium cations with perovskite layers in the DJ phase 2D perovskite endows it with extremely high structural stability, compared with that at only one side in the RP phase one. The devices exhibit a PCE of 13.3% with unprecedented stability, even when subjected to very harsh testing conditions. Full-Text PDF Open Archive
