Dr. Ray obtained his doctoral degree from Indian Institute of Technology, Kharagpur in 2005. He was CSIR senior research fellow (2002-2003), post doctoral fellow at Varaibale Energy Cyclotron Centre (DAE, Govt. of India) and taught 3 years as lecturer at Birla Institute of Technology, Ranchi. Dr. Ray’s current research is focused on development of new photovoltaic materials (binary, ternary and quaternary chalogenides absorbers, new transparent conducting oxides, alternative buffer materials) and solar cells which are eco-friendly and of low cost. thermoelectric and photovoltaic (solar) energy conversion materials and devices. He has an expertise on synthesizing nano-materials by solution routes, electrodeposition, spin casting and spray deposition of thin films, their electrical, optical, thermal and structural characterizations at low (10K-300K) and high temperatures (300K-1500K). His research team is working on ab-initio studies (VASP, Siesta) and device simulation (SCAPS) of predicting opto-electronic properties of novel solar cells as well.
