Background

The field of optoelectronics is experiencing a transformative shift as the global display and lighting industry rapidly moves towards efficient and sustainable technologies. At the forefront of this transformation is the rise of perovskite light-emitting diodes (PeLEDs), which have the potential to redefine traditional optoelectronic applications due to their exceptional properties, including high color purity, solution-processability, and cost-effectiveness. These characteristics have made PeLEDs promising candidates for various applications such as display panels, intelligent lighting, and biological imaging. It's estimated that PeLEDs could contribute to a market valued at 1.5 billion US dollars by 2028. Nevertheless, transitioning PeLEDs from laboratory settings to wide industrial use encounters several technical hurdles, such as maintaining operational efficiency and addressing environmental concerns with current materials.

Despite notable advancements, such as achieving external quantum efficiencies surpassing 20%, PeLEDs still face critical reliability and sustainability issues. Notably, device brightness often declines significantly after prolonged use, and the use of lead-based materials, coupled with the lack of recycling systems, poses environmental risks. To overcome these obstacles, researchers are actively exploring alternatives like lead-free tin-based perovskites, although these alternatives currently yield lower efficiency. Additionally, challenges in achieving uniformity in large-area printing remain unsolved, stalling commercialization potential. The immense potential of PeLEDs lies in surmounting these challenges through innovations in device reliability, solvent-free production methods, and effective recycling solutions.

This Research Topic aims to delve into the comprehensive study of novel optoelectronic functional materials, including both traditional and emerging materials, with the goal of unlocking their potential for sustainable applications. This includes exploring interface regulation, device engineering, and material growth techniques to enhance performance and facilitate commercialization.

To gather further insights into improving PeLEDs and related technologies, we welcome articles addressing, but not limited to, the following themes:
Investigating materials' electronic structures using advanced theoretical and simulation methods.Identifying key factors in the energy conversion process through spectroscopic and optoelectronic analysis.
• Optimizing preparation methods to support industrial applications of optoelectronic materials.
• Improving material surface properties and enhancing optoelectronic performance through advanced modification techniques.
• Modulating material properties such as absorption spectrum, emission wavelength, and carrier mobility.
• Achieving controlled material growth by investigating influences such as temperature, pressure, and reactant concentrations.
• Enhancing device durability through optimized material compositions and advanced packaging technologies.

Topic editors

Frequently asked questions

  • Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

    Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

  • The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

    Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

  • As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

    A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

  • Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

  • Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

    As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

    Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

  • Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.

  • A team of guest editors (called topic editors) lead their Research Topic. This editorial team oversees the entire process, from the initial topic proposal to calls for participation, the peer review, and final publications.

    The team may also include topic coordinators, who help the topic editors send calls for participation, liaise with topic editors on abstracts, and support contributing authors. In some cases, they can also be assigned as reviewers.

  • As a topic editor (TE), you will take the lead on all editorial decisions for the Research Topic, starting with defining its scope. This allows you to curate research around a topic that interests you, bring together different perspectives from leading researchers across different fields and shape the future of your field. 

    You will choose your team of co-editors, curate a list of potential authors, send calls for participation and oversee the peer review process, accepting or recommending rejection for each manuscript submitted.

  • As a topic editor, you're supported at every stage by our in-house team. You will be assigned a single point of contact to help you on both editorial and technical matters. Your topic is managed through our user-friendly online platform, and the peer review process is supported by our industry-first AI review assistant (AIRA).
