BHARTI, Vishal [Ph.D. (AcSIR, New Delhi)]


Dr. Vishal Bharti has received his B.Sc. (2006) and M.Sc. (2008) degrees in Electronics from University of Jammu, Jammu and Kashmir, India. He obtained his Ph.D. degrees from the Academy of Scientific and Innovative Research (AcSIR) at CSIR-National Physical Laboratory, New Delhi, India in 2017 under the direction of Senior Scientist Dr. Vinay Gupta and Emeritus Scientist Dr. Suresh Chand. His doctoral dissertation entitled “EFFICIENT TERNARY BLEND BULK-HETEROJUNCTION ORGANIC SOLAR CELLS WITH FÖRSTER RESONANCE ENERGY TRANSFER” was focused on the dual donor based ternary blend Bulk-heterojunction (BHJ) polymer solar cells (PSCs). He has firstly reported the mechanism of Förster Resonance Energy Transfer (FRET) in dual donor ternary blend system, which is responsible for efficiency enhancement in ternary blend BHJ-PSCs and published his results in highly reputed journal Advanced Materials 27(30), 4398, 2015 and Applied Physics Letters 108 (7), 073505, 2016.
He is a recipient of the SERB-National Postdoctoral Fellowship in Physical Sciences (2017), Indo-Us Bhaskara Advanced Solar Energy (BASE) Fellowship (2014), UGC-Junior Research and Senior Research Fellowship (2010) and Gold Medalist in Master of Science (M.Sc.) in Electronics (2008).
He joined as postdoctoral fellow at Centre for Energy Studies, Indian Institute of Technology Delhi (IIT-D), New Delhi, India since April, 2017.
