Kinetic Regulation of Intercalation-Assisted Crystallization in Hybrid Evaporation-Solution Perovskite Solar Cells.
Hybrid evaporation-solution processing offers a promising route for high-efficiency perovskite solar cells; however, the dense lead iodide (PbI2) framework leads to competing intercalation and dissolution-recrystallization pathways, resulting in incomplete conversion and limited device performance. Here, we report a ki...
