Metal halide perovskites are considered to be a particularly low-cost and promising class of materials for next-generation solar modules. Perovskite solar cells can be produced with coating processes using liquid inks made from precursor materials and various solvents.
Adjusting the Dance Tunes the Melt
Many chemical processes require liquids as solvents, but the liquids often vaporize and release hazardous emissions in the process. Ionic liquids offer a solution because they have low volatility but can have melting points too high for practical use. New research used molecular simulations and experiments to demonstrate how changing the structure of ionic liquids changes their melting point.
