Photoisomeric Molecule-Mediated Ion Anchoring and UV Resistance in Metal Halide Perovskites
ResearchHalide perovskites are novel photovoltaic materials with soft ionic lattice that are continuously exposed to sunlight during operation. High-energy ultraviolet (UV) irradiation will cause halide ion oxidation within the perovskite layer, accelerating ...

Topological polarons in halide perovskites
Proceedings of the National Academy of SciencesHalide perovskites emerged as a revolutionary family of high-quality semiconductors for solar energy harvesting and energy-efficient lighting. There is mounting evidence that the exceptional optoelectronic properties of these materials could stem from unconventional electron–phonon couplings, and it has been suggested that the formation of polarons and

Photophysics of Lead-Halide Perovskite
, 2018 The Sun provides Earth with a greenhouse gas free source of energy that exceeds the annual energy consumption by orders of magnitude. Current solar cell technology limits the percentage of harvested solar energy that can be used to generate electricity; this is why new concepts and materials for photovoltaics are being explored.

Halide segregation in mixed-halide perovskites
, 2021 Metal halide perovskites have garnered a great deal of interest over the last few years due to their impressive – and rapidly increasing – performance as materials for solar cells. In particular, mixed-halide perovskites are essential for use in all-perovskite or perovskite-silicon tandem solar cells due to their tunable bandgap.
