Dr. Jitendra Kumar is a Joint Faculty member in the Department of Physics and the Department of Materials Engineering at the Indian Institute of Technology Jodhpur. His research focuses on advanced semiconductor materials and thin-film photovoltaic technologies for sustainable energy applications.

He completed his B.Tech. in Electronics and Communication Engineering from Uttar Pradesh Technical University, Lucknow, in 2009 and his M.Tech. in Nanotechnology from the Indian Institute of Technology Roorkee in 2011. He received his Ph.D. from the Indian Institute of Technology Kanpur in 2019, where his research focused on the synthesis and characterization of solution-processed Cu₂ZnSnS₄ thin films for solar cell applications.

Following his Ph.D., he worked as an Institute Postdoctoral Fellow at IIT Delhi (2019–2020), focusing on inorganic perovskite nanocubes (CsPbIxBr3−x) for photovoltaic applications. From 2020 to 2023, he was a postdoctoral researcher at Ben-Gurion University of the Negev, Israel, working on (BixSb1−x)₂Se₃-based solar cells. Between August 2023 and April 2025, he served as an INSPIRE Faculty at IIT Dhanbad, where he led research on BaZrS₃ thin-film solar cells. In early 2025, he was a Marie Curie Fellow at the International Iberian Nanotechnology Laboratory (INL).

His research group focuses on developing advanced materials for energy applications, particularly inorganic thin-film solar cells, with emphasis on materials design, device fabrication, and performance optimization for next-generation photovoltaic technologies.
