Synthesis of Hybrid Lead Iodide Perovskite Thin Film by Two-Step Method Modified with a Double Dipping Circle to Control Its Crystallization and Morphology to Improve Solar Cells’ Performance
Scheme 2
The proposed mechanism of dissolution–recrystallization process of perovskite film fabricated by a two-step dipping process explains the formation of voids and defects on the perosvkite film and the large grain size of perovskite crystals [17].
