Abstract
Abstract Hybrid halide perovskites have been identified as an important novel class of photovoltaic absorbers and have proven their great potential with ever record-breaking efficiencies. Some of the more fundamental properties of halide perovskites, however, still are to be properly understood. The ongoing debate as to whether ferroelectricity and/or ferroelasticity play a role in these materials is just one example for this. Herein, I aim to make these phenomena more approachable to the wider research community and elucidate the foundations and consequences of these phenomena.
期刊介绍：
Zeitschrift für Kristallographie – Crystalline Materials was founded in 1877 by Paul von Groth and is today one of the world’s oldest scientific journals. It offers a place for researchers to present results of their theoretical experimental crystallographic studies. The journal presents significant results on structures and on properties of organic/inorganic substances with crystalline character, periodically ordered, modulated or quasicrystalline on static and dynamic phenomena applying the various methods of diffraction, spectroscopy and microscopy.
