High responsivity photodetectors based on FAPbBr 3 perovskite quantum dots–graphene hybrid is represented in the image. As described in article number 1700304 by Jun Wang, Yinglin Song and co‐workers, photogenerated electrons and holes in FAPbBr 3 perovskite quantum dots affected the motion of charges in the graphene channel. The trapped carriers in QDs produced effective photo‐gating effects, lead an ultrahigh photoconductive gain.
