PhD student @NanoDTC, University of Cambridge. Previously, undergrad @IITMadras. Make batteries by day, burgers by night.
Cambridge, UK
Joined February 2020
Delighted that this perspective on photobatteries (the dominant topic of my PhD) is out in @Joule_CP. We highlight limitations in the understanding of the physics of these devices, suggest standardized measurement protocols and realistic use cases!.

@ACSEnergyLett The next time you see a paper claiming photocharging of a Li or Zn metal anode pay close attention to the conduction band positions and anode plating potentials. We suspect that photocatalysed reactions with oxygen leaking through the cell are responsible for the rise in voltage.

Since my PhD began in October 2021, about 30 papers have been published on different materials that can be used in Li & Zn photobatteries. In research published in @ACSEnergyLett we show that the physics of these systems renders 'photocharging' impossible!.

The demand for autonomous off-grid devices has led to the development of “photobatteries”, which integrate light-energy harvesting and electrochemical energy storage in the same architecture. Despite...

Excited to share the final paper from my undergrad. We use a bit of math to produce a single "effective" refractive index for a core-shell nanoparticle. Accuracies far exceed previous theories. Hopefully this will help speed up your plasmonic calculations!

Looking forward to this!.
The NanoDTC twitter account has been taken over by two c2020 students! Anna (@AScheeder) is a biomedical engineer and Arvind (@apujari257) a materials engineer from India. They will join @StranksLab/@group_laser and @BioElSystTech/@KnowlesLabCamb for their mini projects!
