Dear Colleagues,

Metal halide perovskites have emerged as a class of semiconductors materials with unique optoelectronic properties, which enable a broad range of energy-related applications. Since the first application, the photoconversion efficiencies have been boosted up to 25% within a few years, but to go toward the commercialization, the scientific community is focusing the efforts on the contemporary challenges associated with the limited operational stability of hybrid perovskites, and on the replacement of lead (Pb) with less toxic metals, commonly tin (Sn). This Special Issue of Nanomaterials aims to publish original research papers and review articles directing on the innovative synthesis and application of stable and/or lead-free perovskite, in the form of methylammonium-free perovskite, nanocomposite perovskite-additives, 2D and quantum dots, in order to understand the fundamental degradation mechanisms and address them. Recent advances in towards deepening the understanding of the nature of instabilities in hybrid perovskite materials and the corresponding devices from the perspective of structural properties and optoelectronics as well as device operation will be covered.

In this Special Issue, we aim at providing a timely perspective on the advances in perovskite optoelectronics, related to the stabilization strategies. Topics to be covered include (but are not limited to):

• Chemi-structural strategies to stabilize hybrid perovskites
• Low-dimensional perovskites towards stable devices
• Stability of hybrid perovskite devices under real-world operation conditions
• Lead-free stable perovskite synthesis and optical properties
• Advanced optoelectronic devices (solar cells, LEDs)
• Photocatalysis

Experimental and theoretical contributions are both welcome.

Accepted papers are published in the joint Special Issue in Nanomanufacturing or Nanomaterials (https://0-www-mdpi-com.brum.beds.ac.uk/journal/nanomaterials/special_issues/Nano_Optoele_Perov).

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. Nanomanufacturing is an international peer-reviewed open access quarterly 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 1000 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.
