Halide Perovskite Photovoltaics: Background, Status, and Future Prospects.

Chemical Reviews, 2019
The photovoltaics of organic-inorganic lead halide perovskite materials have shown rapid improvements in solar cell performance, surpassing the top efficiency of semiconductor compounds such as CdTe and CIGS (copper indium gallium selenide) used in solar

Excitons in CsPbBr3 Halide Perovskites

The Journal of Physical Chemistry Letters, 2021
Excitons in Bridgman grown halide perovskite CsPbBr3 single crystals were examined using photoluminescence (PL) spectroscopy to determine the nature of the electronic states. The photoluminescence intensity was strongly temperature-dependent and depended upon the specific exciton band.

Ferroelectricity in Ultrathin Halide Perovskites

Nano Letters
Ferroelectricity has recently been demonstrated in germanium-based halide perovskites. We use first-principles-based simulations to study 4-18 nm CsGeBr3 films and develop a theory for ferroelectric ultrathin films. The theory introduces (i) a local order parameter, which identifies phase transitions into both monodomain and polydomain phases, and (ii)

Metal halide perovskites

Η ολοένα αυξανόμενη ανάγκη παρακολούθησης ατμοσφαιρικών ρύπων, τοξικών χημικών και εκρηκτικών αερίων, έχει ωθήσει σε σημαντικές εξελίξεις στον τομέα της τεχνολογίας ανίχνευσης αερίων. Ωστόσο, οι συμβατικοί αισθητήρες αντιμετωπίζουν συχνά περιορισμούς, όπως χαμηλή ευαισθησία και επιλεκτικότητα.
