Dr Devendra Tiwari

VC Senior Fellow

Department: Mathematics, Physics and Electrical Engineering

Short Bio

I have joined Northumbria University in 2020 as a Vice-Chancellor's Senior Fellow in the Department of Mathematics, Physics and Electrical Engineering. My current research interest lies in understanding the emergence of defect-tolerance in semiconductors and using defect-tolerant semiconductors for PV and solar fuel applications. This involves materials discovery and building structural-activity relationship through a combination of atomistic computational modelling, materials processing and defect-characterization of new inorganic PV semiconductors and devices. I have developed novel methodologies to process complete solar cells using non-vacuum techniques, examining a variety of unconventional absorbers including Cu2SnS3, Cu2ZnSn(S,Se)4, BiFeO3, BiI3, BiSI, BiPS4. Recently we have been investigating these methodologies to develop PV structures for low-cost system integration (buildings, automotive, etc.) as well.

​My postdoctoral studies were undertaken at the University of Bristol in Professor David Fermin's lab as a part of an EPSRC project targeting new PV technologies based on solution-processable earth-abundant materials. Before this, I studied chemistry from Sardar Patel University, Gujarat, India (MSc 2009) and completed my PhD in 2014 investigating solution-processed Cu2SnS3 thin-films for solar cells at Dr K. C. Patel research and development centre (CHARUSAT, India) through a UGC-department of atomic energy (DAE) fellowship. My thesis work focused on low-temperature charge-transport measurements and photoemission experiments on semiconductor thin-films and PV devices.
