In article no. 1900041 , Wenxiu Que and co‐workers propose a facile method to effectively improve the electronic properties of the effective electron transport layer by adding an aluminum chloride precursor solution into a SnO 2 quantum dots solution. Thus, the conductivity and film coverage of the SnO 2 film and the energy band alignment at the SnO 2 /perovskite interface have significantly improved, thereby improving the power conversion efficiency of the devices.
