Herein, for the first time, the role of double‐layer electron transporting layer (ETL), i.e. ZnO/SnO 2 on the efficiency of lead sulfide quantum dots solar cells is demonstrated. Using this approach, a device with power conversion efficiency of 10.6% is achieved mainly due to the enhancement of open circuit voltage ( V OC ). The authors reduce the loss‐in‐potential by 80 mV using ZnO/SnO 2 double‐layer ETL.
