Abstract

For stability issues in perovskite-based optoelectronic devices, ionic transport is the most urgent to be addressed. The mobile ions will bring in a growing number of charged defect and phase segregation to perovskite layer; they will cause interfacial energetic distortion and defects generation, which will greatly deteriorate the device performance. Thus, a deep understanding of the ionic transport in perovskite material is of vital importance in fabricating long-term stable perovskite solar cells (PSCs). In this chapter, we systemically introduce the theoretical basis and the relevant characterization methods of ionic transport. Then, we summarize the factors governing ionic transport in perovskite film and their impacts on the performance of PSCs. Light illumination, organic cations, grain boundaries, residue lattice strain, and moisture have been found to accelerate ionic transport. Strategies developed to suppress the ionic transport in PSCs are also described in each section.
