Monolithic all-perovskite tandem solar cells with 24.8% efficiency exploiting comproportionation to suppress Sn( ii ) oxidation in precursor ink

TL;DR: Lin et al. as discussed by the authors used metallic tin to prevent oxidation in mixed Pb-Sn narrowbandgap perovskites to reduce the Sn4+ (an oxidation product of Sn2+) to Sn2+ via a comproportionation reaction.
Journal ArticleDOI

All-perovskite tandem solar cells with 24.2% certified efficiency and area over 1 cm2 using surface-anchoring zwitterionic antioxidant

TL;DR: Xiao et al. as mentioned in this paper used strongly reductive surface-anchoring zwitterionic molecules to suppress Sn2+ oxidation and passivate defects at the grain surfaces in mixed lead-tin perovskite films, enabling an efficiency of 21.7% (certified 20.7%).
Journal ArticleDOI

All‐Inorganic Perovskite Nanocrystals for High‐Efficiency Light Emitting Diodes: Dual‐Phase CsPbBr3‐CsPb2Br5 Composites

TL;DR: In this article, a dual-phase all-inorganic composite CsPbBr3-CsPb2Br5 was developed and applied as the emitting layer in LEDs, which exhibited a maximum luminance of 3853 cd m-2, with current density (CE) of ≈8.98 cd A-1 and external quantum efficiency (EQE) of 2.21%, respectively.
