Abstract
The present disclosure relates to a mixture that includes a perovskite precursor, a solvent, and an additive that includes at least one of a first amine, a ketone, an aldehyde, a non-nucleophilic sterically hindered base, and/or a halogen-containing compound, where, upon removal of the solvent and the additive, the perovskite precursor is capable of being transformed into a perovskite.
Claims23
A mixture comprising:
- a perovskite precursor;
- a solvent;
- and
- an additive comprising 4,4-dimethyl-2-pentanone, wherein:
- the additive is present at a concentration relative to the solvent between greater than 0% v/v and less than or equal to 20% v/v, and
- upon removal of the solvent and the additive, the perovskite precursor is capable of being transformed into a perovskite.

A method comprising:
- combining a perovskite precursor, a solvent, and 4,4-dimethyl-2-pentanone to form a mixture;
- applying the mixture to a substrate;
- and
- treating the mixture, wherein:
- the 4,4-dimethyl-2-pentanone is present at a concentration relative to the solvent between greater than 0% v/v and less than or equal to 20% v/v, and the treating results in the removing of at least a portion of the solvent and the 4,4-dimethyl-2-pentanone additive and the forming of a perovskite.
