All‐inorganic perovskite CsPbX3 (X = Cl, Br, I) and related materials are promising candidates for potential solar cells, light emitting diodes, and photodetectors. Here, a novel architecture made of CsPbX3/ZnS quantum dot heterodimers synthesized via a facile solution‐phase process is reported. Mic...
