Special Issue Information
Dear Colleagues,
Metal halide perovskites have rapidly emerged as one of the most promising classes of materials for next-generation optoelectronic technologies, including solar cells, light-emitting diodes, photodetectors, and radiation imaging devices. Their outstanding optical absorption, long carrier diffusion lengths, tunable band structures, and compatibility with low-temperature fabrication offer exceptional opportunities for the development of high-performance and low-cost energy and photonic systems. In the context of global trends such as carbon-neutral energy transitions, lightweight flexible electronics, and scalable manufacturing, perovskite-based technologies represent a transformative path toward practical, sustainable, and high-efficiency devices. However, despite remarkable achievements, challenges such as interfacial defects, ion migration, environmental instability, and limited device longevity continue to restrict progress toward commercialization. Interfaces—between perovskites and charge-transport layers, electrodes, or passivation molecules—play a decisive role in determining charge transport, defect passivation, structural evolution, and operational durability, making interface engineering central to both scientific discovery and technological implementation.
This Special Issue aims to gather and disseminate the most recent advances related to interface engineering, defect control, materials chemistry, and device optimization in perovskite optoelectronics. We welcome contributions that deepen the understanding of structure–property–function relationships in perovskite materials and align with the Materials journal’s focus on bridging fundamental materials science with engineering applications. The scope of this Special Issue fits the journal’s aims by covering material synthesis, interfacial physics, charge-transport mechanisms, stability engineering, and advanced characterization methodologies spanning the nanoscale to the device level.
In this Special Issue, original research articles and reviews are welcome. Research areas may include, but are not limited to, the following:
- Interface engineering, defect passivation, molecular coordination, and energy-level alignment
- Charge-transport layers and interlayers for perovskite optoelectronic devices
- Ion migration, structural stability, and degradation mechanisms
- Carrier dynamics, recombination mechanisms, and device physics
- Large-area processing, coating technologies, encapsulation, and scalable fabrication
- Advanced characterization and multi-scale modeling of interfacial processes
We look forward to receiving your contributions.

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-anonymized 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.
