Crystal Structures and Applications of Perovskite Halides in Solar Cells

Dear Colleagues,

Perovskite solar cells (PSCs), which utilize perovskite halide materials as the light-absorbing layer, offer significant advantages such as low cost, flexible processing, solution-based fabrication, and high efficiency, making them highly promising for practical applications. The exploration of crystal structures in perovskite halides has significantly advanced our understanding and application of these materials in PSCs.

This Special Issue focuses on recent breakthroughs in the crystal chemistry of perovskite halides and their implications for photovoltaic technology. It provides a comprehensive overview of various perovskite halide compounds, detailing their crystallographic properties investigated through advanced techniques like X-ray diffraction and transmission electron microscopy. For practical applications, the formation of highly crystalline-oriented grains in thin-film configurations is critical, as these features significantly influence the photovoltaic performance of PSCs.

This Special Issue reviews recent progress in the fabrication of high-quality perovskite films, highlighting the correlation between film morphology, crystalline quality, and power conversion efficiency. Furthermore, it addresses future challenges and the prospects for commercialization, providing a roadmap for the development and deployment of PSC technology.

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 250 words) can be sent to the Editorial Office for assessment.

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. Crystals is an international peer-reviewed open access monthly 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 2100 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.
