Special Issue Information
Dear Colleagues,
Perovskite materials have shown good application prospects in optoelectronics and photovoltaics due to their unique structural advantages. How to control the local structure of perovskite materials based on the original structure and performance advantages, to explore potential high performance and new properties, is of great significance to further expanding the application prospects of such materials. In recent years, with the deepening of research, its conversion efficiency in the field of photovoltaics has continued to rise, from the initial single digits to more than 25 %, and has gradually become a research hotspot of energy materials. The common preparation methods of perovskite materials include the high temperature solid phase method, sol–gel method, hydrothermal synthesis method, and vapor deposition method. Doping is an important means to regulate the physical properties of halide perovskites and even induce them to produce new properties. In view of the structural characteristics of the vacancy configuration of the double perovskite Cs2BX6, different ions can be easily doped, especially the 6-coordinated tetravalent cation B position. After ion doping, due to the different ionic radii, local distortion of the octahedral structural unit is caused, the symmetry of the local structure is reduced, a local potential well is generated, and the transition from free exciton to self-trapped exciton is induced. It is expected to break the odd–even forbidden transition and provide additional emission centers to excite the novel photoelectric properties of perovskite. Therefore, it can be foreseen that regulating the local behavior of double perovskite octahedral units is expected to optimize their physical properties.

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. Crystals is an international peer-reviewed open access monthly journal published by MDPI.
