I am a dedicated and inquisitive master's student at Jahangirnagar University, specializing in the captivating field of solid-state physics. My current research revolves around employing Density Functional Theory (DFT) to explore the promising properties of cubic FATaX3 perovskite structures, where X can be iodine (I), bromine (Br), or chlorine (Cl).In my quest to unravel the mysteries of these intriguing materials, I am delving into their electronic and structural characteristics, with a specific focus on their potential applications in photovoltaics. This involves rigorous theoretical simulations, data analysis, and a keen eye for detail to elucidate how these perovskite structures can revolutionize the field of solar energy conversion.By actively contributing to the scientific community, I aspire to further our understanding of these materials, pushing the boundaries of knowledge in solid-state physics and renewable energy. Collaboration and knowledge exchange are integral to my academic journey, and I am excited to connect with fellow researchers, share insights, and explore the exciting possibilities that this research area offers.
