I received an MPhys degree in Physics from Corpus Christi College, Oxford in the summer of 2019. For my master's project I studied electroluminescence imaging of metal halide perovskite optoelectronic devices supervised by Prof. Henry Snaith and Dr Bernard Wenger. I constructed apparatus consisting of a scientific camera and a source meter with contacts for applying a voltage to the terminals of the devices. Using this system I studied devices created by other group members such as 2D/3D hybrid perovskite LEDs and large surface area perovskite solar cells. This experimental tool proved valuable for investigating spatial inhomogeneity and long term transient changes in the devices.
I am using time-resolved spectroscopy techniques to investigate charge transport in metal halide perovskites (MHPs). MHPs are a class of semiconducting materials which have great potential as absorbers in next-generation solar cells due to their outstanding optoelectronic properties. Time-resolved techniques use ultrafast lasers to allow charge dynamics to be studied on a timescale of femtoseconds, this makes them a powerful tool for understanding the mechanisms behind charge transport in these materials.
I am currently a demonstrator in the second year undergraduate electronics lab.
