Perovskite solar cells have recently achieved high efficiency of more than 25% and are in the limelight as the next generation solar cells. Although currently showing relatively high efficiencies, much progress is still needed to reach theoretical efficiencies that are close to theoretical efficiencies of the Shockley–Queisser limit. In particular, for developing the extremely high efficient perovskite solar cells, engineering of interfaces 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. Here I would like to discuss the interface engineering and design strategy to achieve high efficient perovskite solar cells. |
