Termination details:

I am currently pursuing a MPhil (by research) in the Optoelectronics group.

Research Interests

My work is largely focused on solving problems related to lack of access to clean and sustainable energy, through scientific and entrepreneurial advances in solar energy conversion technologies.

Broadly the themes I am working/ have worked on are:

  • Solar Energy Conversion Devices
  • Hybrid, Organic and Tandem Solar Cells
  • Spectroscopy (Time Resolved and Steady State)
  • Singlet Exciton Fission
  • Fabrication (and Characterization) of Nano Films and Nano Structures
  • Prototyping instruments for nano fabrication and characterizations
  • Energy Efficient Buildings


  • Optical spectroscopy
  • Energy
  • Hybrid Nanomaterials,
  • Photovoltaics
  • NanoPhotonics
