Understanding the crystallization of triple-cation perovskites assisted by mixed antisolvents for improved solar cell device performance

Lead‐Free Halide Double Perovskites: Fundamentals, Challenges, and Photovoltaics Applications

“…One of the effective strategies for making uniform perovskite films is the antisolvent engineering technique which is widely used in lead halide perovskite films. [ 54 ] The dripping of an antisolvent leads to the supersaturation state of the solution which is the driving force for good crystallization. In the case of double perovskites, Gao et al.…”

Crystallization Kinetics of Perovskite Films by a Green Mixture Antisolvent for Efficient NiOx-Based Inverted Solar Cells

“…There are various preparations to fabricate high-quality perovskite thin films for the solar cell applications, including the spin-coating, blade-coating, printing, dipping, vapor evaporation, vapor-assisted deposition, solvent-additive coordination . The antisolvent-assisted crystallization (ASAC) approach is an effective technology to improve the qualities of the perovskite thin film with low-energy consumption, including adjusting the morphology, controlling the thickness, and decreasing the grain boundary. − The extensive use of antisolvents in the traditional preparations of PSCs, such as toluene (Tol), chlorobenzene (CB), and chloroform (CF), has caused environmental and health concerns due to their nonnegligible toxicity, which severely affects the sustainability of PSCs. − Therefore, it is urgent to explore more green and efficient antisolvents to replace toxic antisolvents for the target of sustainability.…”
