Ultrafast solar‐blind UV detection, enabled by a hybrid inorganic perovskite CsPbX 3 quantum‐dot radial junction architecture, achieves rise/fall response times of 0.48/1.03 ms and a high responsivity of 54 mA W −1 at 200 nm without an external power supply, as described by Linwei Yu, Xiangxing Xu, and co‐workers in article number 1700400 . These results pave the way toward large‐area manufacturing of high‐performance Sibased perovskite UV detectors in a low‐cost procedure.
