Dr Hemant Kumar Mulmudi



PhD, M.Sc., B.Tech


Hemant Kumar Mulmudi, PhD, is currently working as a research fellow at the Research School of Engineering.  

His research interests span from synthesizing nanomaterials via inexpensive solution-processed methods to integrating them in solar photovoltaic devices and fuel cells.

His research highlights include the first demonstration of stable lead-free perovskite solar cell (cesium tin iodide) using solution processed methods and investigation of phase segregation and quantum yield of perovskite films for application in silicon-perovskite tandem solar cells. The latter has provided insights into the particle wave-matter interaction at the nanoscale regime. His interests span on developing new characterization techniques to investigate the reliability of opto-electronic devices such as solar cells and modules.


2010-2014: Doctor of Philosophy (PhD) in the School of Materials Science and Engineering at Nanyang Technological University, Singapore.

Topic: Investigating hematite nanostructures for photovoltaic applications.

2007-2009: Masters of Science (M.Sc.) in Advanced Materials (Nanotechnology), University Ulm, Ulm, Germany.

Master thesis: Application of cross-sectional nanoindentation to investigate mechanical stability of complex back-end-of-line (BEOL) stack at Cu\low-K interface. Performed at the Centre for Complex Analysis (CCA), GLOBALFOUNDRIES, Dresden, Germany.

2003-2007: Bachelors of Technology (B.Tech) in Metallurgical and Materials Engineering, Indian Institute of Technology, Roorkee, India.
