Hybrid Halide Perovskite-based solar cells have received unprecedented attention among the photovoltaic community owing to their low-cost and facile solution based fabrication processes. With continuous advancements, this class of solar cells has revolutionized the photovoltaic scenario with an incredible improvement in power conversion efficiency from just 3.8 % to recently certified value that is approachable to commercialized Silicon solar cells technology. The main focus of our group is to enhance the stability as well as the efficiency of perovskite-based solar cell devices.

Particle accelerators allow us to test the governing forces and interactions between incredibly small cracks of visible matter. Big accelerators such as Large Hadron Collider (LHC) have produced collision energy ranging from GeV to TeV, and in the coming years, enormous-sized accelerators with high energies are planned, which will become more expensive. The two primary external limits for accelerator performance are size and energy consumption, both of which are ultimately determined by cost. Despite these drawbacks, conventional accelerators have allowed ground-breaking discoveries and contributed significantly to our understanding of basic physics. There is a persistent interest in creating novel accelerator technologies, such as compact accelerators and plasma-based accelerators, which could get around some of these restrictions and expand the boundaries of the study.

In comparison to conventional accelerators, plasma accelerators offer the possibility of accelerating gradients of high orders of magnitude.

Density Functional Theory (DFT) is a simulation method used in computational materials science to examine the structural, electronic, magnetic, and optical properties, etc. of many-body systems. Our group basically determine these properties of Novel materials for magnetism and spintronics (2D materials, 2D van der Waals' heterostructures, DMS and Heusler compounds), Photovoltaics (Hybrid Haldie Peroskites, Quantum Dots), thermoelectrics and energy storage. The computational codes mainly used are WIEN2k, VASP, Quantum Espresso, and Gaussian. The calculations for the same are being done on various HPC servers in parallel environment.
