Summary
Chalcogenide perovskites (e.g., BaZrS₃, SrZrS₃) have emerged as a promising class of stable, non-toxic, and earth-abundant semiconductors for next-generation optoelectronics and photovoltaics, offering an alternative to lead-halide perovskites. This Special Issue aims to capture the rapid advances in synthesis, characterization, defect engineering, and device integration of chalcogenide perovskite materials.
This Special Issue focuses on the latest developments in chalcogenide-based perovskite materials, including their synthesis (thin films, nanostructures, bulk crystals), structural and optoelectronic characterization, defect and interface engineering, computational materials design, and applications in solar cells, photodetectors, LEDs, and photocatalysis. Both experimental and theoretical contributions are welcome. The goal is to accelerate the understanding of structure-property relationships and to overcome current challenges in stability, carrier transport, and device performance, thereby establishing chalcogenide perovskites as a viable platform for sustainable energy and optoelectronic technologies.
Therefore, this special issue focuses on chalcogenide-based perovskite materials for next-generation optoelectronics and photovoltaics. The following subtopics are the particular interests of this special issue, including but not limited to:
1. Synthesis and processing of chalcogenide perovskite thin films and nanostructures
2. Defect chemistry and doping engineering
3. Interface and charge transport layer design
4. Lead-free and environmentally stable chalcogenide perovskites
5. Computational discovery and high-throughput screening of new compositions
6. Device physics: solar cells, photodetectors, LEDs, and photocatalysis
7. Scalable fabrication and long-term operational stability
