Perovskite Solar Cells: Effect of the Microstructure of the Functional Layers on the Efficiency of Perovskite Solar Cells (Adv. Mater. 20/2017)

Pinhole-free, dense perovskite films with large grains, which can be achieved by control of the nucleation and crystal growth, are essential for high-performance perovskite solar cells. These perovskite-solar-cell systems are discussed by Fuzhi Huang, Yi-Bing Cheng, and co-workers in article number 1601715.
