Research

Theoretical and Computational Chemistry, Material Chemistry

The broader theme of our research is chemical bonding across the periodic table. We try to understand the factors deciding the structure, bonding, reactivity, and properties of compounds because that knowledge will allow us to tune these factors in a desirable way. We translate the concepts of molecular chemistry to extended solid-state structures, with the intention to make Material Chemistry friendlier to chemists. This way, we are trying to tackle relevant technological problems such as the instability issues of lead iodide-based perovskites, which hinder the commercialization of perovskite-based solar cells. We also try to design new materials which can be potential solar absorbers and can be a good substitute for unstable and toxic lead iodide-based perovskites. We also work on materials that exhibit the property of photo-induced phase transition and self-healing
