Part III Students

William Drake

Shaoni Kar

The aim of William's part III project is to understand how the structures in a solar cell affect the light management on all length scales, with a particular focus on optimising the textured architectures in perovskite-silicon tandem devices to maximise light absorption and photon recyling. This will involve a combination of analytical and computational methods alongside experimental measurements of spatially resolved photoluminescence, transmission and reflection spectra. Outside of Physics, William is a keen jazz pianist, cyclist and hill walker. Started November 2018.

After her undergraduate at the University of Delhi in India, Shaoni joined Cavendish for an MASt in Physics. As her Part III Project, she will be trained in the design and fabrication of photonic structures based on metal oxide layers by solution processing methods. The photophysical properties of these systems will then be characterised through various techniques. Beyond physics, she teaches and performs Indian classical dance and loves to compose poetry. Started November 2018.
