This Special Issue concerns the application and characterisation of hybrid halide perovskites, which have, over the last few years, become the focus of the photovoltaic research community. The fast enhancement of the related solar cell performance is due to their unique photophysical properties, such as remarkable optical absorption across a wide range of the solar spectrum, ambipolar charge transport, and long charge carrier diffusion lengths. Hybrid halide perovskites have an ABX3 structure (where A = methylammonium, formamidinium rubidium, caesium; B = tin, lead; X = iodine, chlorine, bromine) and thin films can be grown by different methodologies ranging from vacuum technologies to wet chemistry. Moreover, the need to attract industrial interest is leading to the development of new deposition methods that allow us to obtain uniform layers on a large scale, which can be used in stand-alone devices or in conjunction with other solar cells to increase the final efficiency in a multijunction configuration. Mixing the cations and/or the halides, perovskite with band gap from 1.1 to 3.0 eV can be obtained and, therefore, this class of materials is also attractive for applications in lasing, light-emitting and thermoelectric devices, sensing, and photodetectors. Thus, the research on hybrid halide perovskites is highly various, and it depends on the final application, which also affects the choice of characterization technique. The peculiarities of this material, however, make it challenging to set up a protocol for measuring performance and their operational stability. Lately, tracking the maximum power point is increasingly considered a reliable method for checking the photovoltaic performance, but in other optoelectronic technologies the characterisation procedures must still be well defined.
Original research papers and review papers related to the application and characterisation of hybrid halide perovskites are welcome. The use and characterisation of hybrid halide perovskites reported in the same study are preferred, but applications or characterisation techniques will also be considered for publication.
