Special Issue Information
Dear Colleagues,
Lead halide perovskite thin films have been receiving increasing attention in the last few years, initially stimulated by the impressive improvement in the performance of perovskite solar cells, recently reaching a record power conversion efficiency close to 23 %.
Beyond the excellent photovoltaic properties, lead halide perovskites also show excellent optical properties, including high photoluminescence quantum yield (QY), tunable emission from the blue to the near infrared, and high optical gains at room temperature. All these properties, together with the possibility of the realization of thin films from solutions, make halide perovskites the most promising novel class of semiconductor for photonics and optoelectronic applications.
The research into perovskite is very broad and includes the development of methods for active materials synthesis and their deposition, the investigation of fundamental electronic properties, and the realization, characterization and optimization of solar cells, light emitting diodes and optically pumped lasers.
Concerning the materials development, different families of perovskites have been realized to date, including organic–inorganic lead halides, fully inorganic lead halides, and lead-free perovskites, allowing the realization of both solution-processed bulk thin films and of nanocrystals with a controlled shape, size and chemical composition.
It is also interesting that even if some of these materials have been exploited for the realization of devices with quickly improving performance, many basic aspects of the photophysics of perovskites are still unclear and the subject of debate, like the nature of the emitting species (excitons or free carriers), the role of defects, and the origin of the temperature dependence of the emission properties.
This Special Issue aims to describe the actual state of the art of the wide research on perovskite semiconductors, including the open issues that still require a fuller understanding, and possible future development directions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs).
