I am currently working on simulation and characterisation of charge and ionic transport in perovskite semiconductors under the supervision of Dr Piers Barnes of Prof Jenny Nelson. I am the lead developer of Driftfusion, our home-brewed drift diffusion simulation tool for modelling solar cells with mixed ionic-electronic conducting absorbers layers. I am particularly interested in how mobile ionic charge alters the interpretation of data obtained from optoelectronic measurements and the role that simulation can play to further our understanding of the physics of optoelectronic devices.
