Our research group is dedicated to the development of next-generation photovoltaic technologies, focusing on cost-effective, high-efficiency, and environmentally sustainable materials. We focus on earth-abundant kesterite (CZTS) and chalcopyrite (CTSe, CIS, CISSe) semiconductors, utilizing novel synthesis approaches such as solution processing and hot-injection methods to achieve precise control over composition, phase purity, and defect density.1<\/sup> These strategies enhance optoelectronic properties, making them viable for cost-effective and scalable photovoltaics. A significant portion of our research is dedicated to perovskite solar cells, where we develop high-efficiency all-inorganic and hybrid perovskites, leveraging phase engineering and graded junctions to push efficiency beyond existing limits.2<\/sup> Furthermore, we investigate the fundamental properties of lower-dimensional halide perovskites (2D and quasi-2D) while exploring interface-driven and loss mechanism-centric phenomena in 3D\/2D heterostructures, aiming to optimize charge transport, minimize recombination losses, and enhance long-term stability for photovoltaic applications.<\/p>\n\n\n\n

Our studies also extend to lead-free double perovskites, such as Cs\u00e2\u201a\u201aAgBiCl\u00e2\u201a\u2020, exploring their self-trapping effects and potential as environmentally sustainable alternatives for device applications.3<\/sup> By integrating innovative materials with advanced device engineering, we aim to create highly efficient, stable, and commercially viable solar cells, contributing to the global transition toward sustainable energy solutions.<\/p>\n\n\n\n
