Gas-Induced Formation/Transformation of OrganicāInorganic Halide Perovskites
The recently discovered gas-induced
formation/transformation (GIFT) of organicāinorganic halide
perovskites (OIHPs) represents unprecedented phenomena. The GIFT phenomena
have not only revealed surprising properties of the fascinating OIHP
materials but also showed tremendous promise in various applications,
including solar cells, optoelectronics, sensors, and beyond. After
briefly reviewing recent progress in the exploration and understanding
of GIFT, a perspective on the future research directions in this area
is provided herein. Also provided is a discussion on the significance
of future mechanistic studies in unraveling the rich chemistry and
materials science underlying GIFT and in exploring more potential
applications
Exceptional Grain Growth in Formamidinium Lead Iodide Perovskite Thin Films Induced by the Ī“ātoāĪ± Phase Transformation
The
annealing of fine-grained (ā¼0.175 Ī¼m) āyellowā
Ī“-FAPbI<sub>3</sub> nonperovskite thin films at 100 Ā°C
in dimethyl sulfoxide vapor for a few minutes results in exceptional
grain growth (ā¼5 Ī¼m) induced by their transformation
to the desirable āblackā Ī±-FAPbI<sub>3</sub> perovskite
phase. Mechanistic insights into this unprecedented phenomenon are
provided
