Dr. Naba Kumar Rana is a Postdoctoral Research Fellow at the Department of Chemistry, Bar-Ilan Institute for Nanotechnology and Advanced Materials, Bar-Ilan University, Israel since June 2025. His research focuses on “Flexible inorganic interfaces for high-efficiency charge extraction” for next-generation photovoltaic devices. His work integrates expertise in thin-film deposition, spectroscopy, device fabrication, and characterization with the goal of advancing renewable energy technologies and optoelectronic devices.
Dr. Rana earned a B.Sc. in Physics (Honours) from Vidyasagar University, Medinipur, West Bengal, India, and an M.Sc. in Pure and Applied Physics from the Central University of Chhattisgarh (GGV), India. He completed his Ph.D. in Physics at the Indian Institute of Technology (IIT) Bhilai in December 2024. His doctoral research focused on “Interface Engineering of Perovskite and ETL/HTL Layers for Highly Efficient and Stable Perovskite Solar Cells.”
During his Ph.D., he gained significant expertise in perovskite solar cell fabrication, presented his work at national and international conferences, and published in several peer-reviewed journals. In recognition of his contributions, Dr. Rana was awarded the prestigious CSIR-Direct SRF Fellowship (Govt. of India) in 2024. He also received the DST Nano-Mission JRF in 2019 and the DST-Solar Challenge Award Scheme SRF in 2023 (Govt. of India).
During his Ph.D., he worked on several Government of India funded projects, including:
- Large-area, semi-flexible, and indium-free mixed halide perovskite solar cells.
- Development of large area (152.4 mm × 152.4 mm) >23% heterojunction perovskite solar cells, and >25% efficiency tandem cells (50 mm × 50 mm).
- Synthesis of ZnO nanostructures by wet chemical method and studying visible emission from ZnO nanorods.
Following his Ph.D., Dr. Rana broadened his research interests to include interfacial engineering of perovskite solar cells, large-area device fabrication, perovskite-based photodetectors, and perovskite-based memristors, with the broader aim of addressing challenges in device physics.
Beyond research, Dr. Rana is enthusiastic about mentoring students, fostering collaborations, and contributing to the academic community. He welcomes opportunities to connect with fellow researchers and potential collaborators in perovskite solar cells and device engineering.
