Postdoctoral Research Assistant (PDRA) in Condensed Matter Physics, University of Oxford, UK (Advisor: Prof. Henry Snaith FRS)

Explore vacuum deposited halide perovskites for efficient and stable light emitting diodes (LEDs) and multijunction solar cells.
Probe the light and heat stability of quantum-well heterostructures of low-bandgap 3D perovskites with wide-bandgap 2D perovskites.
Understand the air degradation mechanism of low dimensional mixed lead-tin perovskites.
Synthesize high quality single crystalline perovskite thin films for photovoltaic and LED applications.

PhD Candidate, Cavendish Laboratory, University of Cambridge, UK (Advisor: Prof. Samuel D Stranks)

Studied the various unique fundamental characteristics of mixed lead-tin halide perovskite material systems (processed by spin coating) using a combination of structural, chemical, photophysical and electrical characterization techniques.
Integrated these as absorbers in high mobility field effect transistors and high efficiency single junction perovskite solar cells.

M. Eng. candidate, National University of Singapore, Singapore (Advisors: Prof. Armin Aberle & Dr. Selvaraj Venkataraj)

Investigated high mobility and high near-infrared (NIR) transparent cerium doped indium oxide thin films deposited by DC magnetron sputtering as a possible alternative to indium tin oxide (ITO) for thin film solar cell applications.

Research Assistant (RA), Solar Energy Research Institute of Singapore (SERIS), Singapore (Advisors: Prof. Armin Aberle & Dr. Selvaraj Venkataraj)

Set up the CIGS solar cells R&D pilot line in Singapore. Contributed to the development of novel transparent oxide materials at SERIS in collaboration with PVComB, Germany.

B.Tech Final Year Project, National Institute of Technology Silchar, India (Advisor: Prof. Trupti Ranjan Lenka)

Predicted the electrical characteristics of InGaP/InP tandem solar cells as a function of different absorber parameters and incident solar intensities using TCAD simulation.

Summer Research Fellow (SRF), Bhabha Atomic Research Centre (Chemistry Division), India (Advisor: Dr. C.A. Betty)

Examined the photoelectrochemical properties of ZnO-bare-Si and ZnOporous-Si heterojunctions fabricated using Langmuir-Blodgett method for water splitting applications to generate green hydrogen.
