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.

钙钛矿光电探测器：敏感和稳定的锡铅混合钙钛矿光电探测器，通过双面表面钝化实现红外上转换检测（26/2020小型）

Liang Shen及其同事在文章编号2001534中演示了一种灵敏且稳定的钙钛矿型Sn-Pb钙钛矿光电探测器，该探测器使用碘乙基碘化铵完成了针对薄膜顶部和底部的钝化钝化。双面表面钝化工程可以促进晶粒长大，降低陷阱态的密度并提高表面疏水性。最后，它实现了红外上转换可视化应用。
