The development of highly efficient single junction and multi-junction photovoltaics, coupled with the rise of bright and efficient LEDs with high fidelity and a wide color gamut, has placed halide perovskite materials at the centrestage of next generation technologies aimed towards combating climate change and promoting sustainability. During my PhD, I investigated the intriguing optoelectronic properties of solution-processed mixed lead-tin halide perovskites using a combination of fundamental spectroscopic investigation and applied device integration in solar cells and transistors. In my current postdoctoral role in the group of Professor Henry Snaith at Oxford, my research primarily focuses on the fabrication and characterization of novel ‘superlattice’ architectures (using both solution processing and vacuum thermal evaporation) for efficient and stable perovskite LEDs, as inspired from the well established III-V quantum well LED technology. Moreover, I will also continue to work with mixed lead-tin perovskites by exploring newer avenues for these interesting materials in solar cells and LEDs.
Since October 2023, I have joined Worcester College, University of Oxford as a Junior Research Fellow in Sciences.
