Dr. Ansuman Halder obtained his B.Sc. degree from Scottish Church College, University of Calcutta, in 2011 and then joined the M.Sc.-Ph.D. dual degree program at the Department of Energy Science and Engineering, Indian Institute of Technology (IIT) Bombay, Mumbai. He pursued his Ph.D. under the supervision of Prof. Shaibal K. Sarkar and received his dual degree in 2020. His research work was focused on understanding the structural and opto-electronic properties of various hybrid halide perovskite materials for photovoltaic applications.
Besides publishing several research articles in reputed international journals, Dr. Halder filed a patent for development of perovskite based thermochromic photovoltaic devices during his Ph.D. He was awarded the prestigious Bhaskara Advanced Solar Energy (BASE) fellowship in 2017 for a 3 month internship at the National Renewable Energy Laboratory (NREL), Colorado. After finishing his Ph.D., Dr. Halder joined Bar-Ilan University, Israel in 2020 as a postdoctoral fellow and worked with Prof. David Cahen to understand the electrical and electronic properties of hybrid perovskite materials.
Use of solar power for energy generation is highly advantageous as it is abundant and pollution free. In recent times, perovskite based solar cells have emerged as one of the most promising technologies to provide solar generated electricity at lower costs. During his Fulbright-Nehru Postdoctoral Research fellowship, Dr. Halder is focusing on understanding the growth dynamics of the large-scale perovskite thin film formation that is essential for development of perovskite based solar cell technology.
