My research is focused on improving out understanding of Perovskite Solar Cells (PSCs) in Alison B. Walker's group at the University of Bath.
In collaboration with Nicola Courtier and Giles Richardson at the University of Southampton and Jamie Foster at the University of Portsmouth, we have built a drift-diffusion model to solve for the dynamics of charge carriers and moving ions in PSCs.
Below is a video I have made of hysteresis in a PSC.
I also work with Krishna Feron and the Centre for Organic Electronics at the University of Newcastle, Australia to understand charge and energy transport in organic solar cells using Kinetic Monte Carlo (KMC) methods.
