Perovskite solar cells have recently achieved high efficiency of more than 25% and are in the limelight as the next generation solar cells. With high efficiency in recent years, perovskite has developed to a level where commercialization is considered. For commercialization, high efficiency and stability of the device must also be considered. To achieve these, charge transport control with minimal recombination is important. Therefore, proper design and engineering of interfaces has become increasingly important in recent years and many studies have been published. There are many interfaces in the perovskite solar cells and if these carrier selection or separation interface is changed, changes in the interface characteristics can change the overall parameters that affect device efficiency and stability. Here I would like to discuss the charge transport control in PSCs by interface Engineering and design strategy to achieve highly efficient and stable perovskite solar cells.
