Artistic Connections

I don’t have any previous connections with music, sorry, but looking forward to hearing what my physics will sound like!


Students from Bertha Park High School, Perth in Scotland are busy writing some music based on my work. It will be performed at the AK Bell Library in Perth on Nov 11th and 12th 2019 – after which it will appear here! MORE DETAILS HERE


During my undergraduate studies, I got convinced that I have a passion for scientific research. I did my studies well to secure admission to a research-oriented University. I was the University topper for both my undergraduate and Master’s degree courses.

After getting a few years of research experience from India, I got UK Overseas Research Studentship to carry out research (Ph.D.) at the University of Strathclyde, UK.

During my Ph.D., I was experimenting on ‘light emission’ properties of materials. After Ph.D., I got interested in ‘light-absorbing material’ to generate electricity and that is how I reached working with SOLAR CELLS.

Scientific Achievements

  • I developed a novel charge-transporting layer for plastic solar cells which have very low defect density at the interface. This research led to the development of organic solar cells with record efficiency (in 2015). This method has been then taken by other researchers in the thin-film solar cells of quantum dot and hybrid perovskites, which worked successfully to their systems as well. Also, this research result was fundamental to the development of ‘flexible solar cells.
  • I am now working on indoor solar cells, i.e solar cells that can harvest indoor light (light inside the buildings) to generate useful electrical energy to power some sensors. Recently I showed that by tuning the absorption properties of the materials, we can maximise the light harvesting potential of these solar cells, inside the buildings too. This research is important because this will advance the Internet of Things technology where we can connect any physical object with an ON and OFF switch to the internet using sensors.
Did You Know?

I am an experimental physicist which means that I have to do experiments that sometimes involved explosions!
