Graphical Abstract

In article number 2001534, Liang Shen and co-workers demonstrate a sensitive and stable Sn-Pb perovskite photodetector, employing phenethylammonium iodide to complete defects passivation aiming the top and bottom of films. The double-sided surface passivation engineering can promote the grain growth, reduce the density of trap states and improve surface hydrophobicity. Finally, it realizes infrared up-conversion application for visualization.
