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

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes
Advanced Optical Materials, EarlyView.Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.

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.
