TL;DR: Yang et al. modify the oxide based electron transporting layer with organic acid and obtain planar-type cells with high certified efficiency of 21.5% and decent stability and success in suppressing hysteresis and record efficiency for planars-type devices using EDTA-complexed tin oxide (SnO2) electron-transport layer.

TL;DR: In this paper, the authors demonstrate cesium cation (Cs+) doped 2D (BA)2(MA)3Pb4I13 perovskite solar cells giving a power conversion efficiency (PCE) as high as 13.7%.

TL;DR: An efficiency of flexible perovskite solar cells (Pvs-SCs) of 16.09% is achieved, the highest value reported for flexible Pvs- SCs to date, attributed to the superior features of alternative electron-transport materials.

TL;DR: A novel dimethyl sulfide (DS) additive is developed to effectively improve the performance of the F-PSCs, revealing that the DS additive reacts with Pb2+ to form a chelated intermediate, which significantly slows down the crystallization rate, leading to large grain size and good crystallinity for the resultant perovskite film.

TL;DR: Experimental analyses reveal that the Nb:SnO2 ETL significantly enhances the electron extraction and effectively suppresses charge recombination, leading to improved solar cell performance.
