A major thrust of the group focuses on the design, synthesis, and photophysical characterization of environmentally benign bismuth- and tin-based hybrid halide perovskites. Funded programmes in this area span fundamental structure-property studies, light detection, photovoltaics, and emerging applications in neuromorphic computing and memristive devices. These projects are supported by DST-SERB, KSCSTE, DST Indo-ASEAN, and CSIR, and are carried out in close collaboration with AGH University of Kraków, Poland, and Osaka University, Japan.
