Perovskite Crystals and Thin Films

Dear Colleagues,

Over the recent years, perovskite materials have evoked a wide response of the research community mainly due to their superior performance in thin film photovoltaic applications. However, perovskites have found their application in many other fields of electronics and photonics (solid states lasers, light-emitting diodes, photodetectors, etc.). The main advantage of perovskites over their inorganic counterparts is low-temperature and low-cost-solution-based deposition on a large variety of the substrates by coating or printing techniques. Most perovskites have long-range ambipolar transport and high absorption coefficients, and it is even very easy to synthesize perovskite crystals by several techniques with the same or even better properties in comparison with their thin films. These crystals, having very low defect density, are good candidates to disclose a variety of significant properties of perovskite materials in general (perovskite crystals and devices based on them have shown unique properties and wide application, such as harvesting solar energy, perovskite photodetectors possessing impressive characteristics for the detection of various wavelengths, etc.). Furthermore, perovskite crystals are high-gain materials for lasing because of their high absorption coefficient, high photoluminescence quantum yield, slow Auger recombination rate, long carrier diffusion length, and low defect density.

In this Special Issue, we would like to cover all important aspects concerning perovskite crystals and thin films, including novel materials, excellent electronic properties, density of states and defects, band gap research studies, space charge transport, thermal properties, stability measurements, or innovations in device architectures.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

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. Materials 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 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
