Guillaume -Zoppi

I am an associate professor in the Department of Mathematics, Physics and Electrical Engineering involved in research and learning and teaching activities.

I graduated from the Université de Savoie in France in 1998 with a DUT "Mesures Physiques". I then joined Northumbria University where I completed a BSc (Hons) in Applied Physics and MSc in Optoelectronics & Communication Systems. I was awarded a PhD in Physics from Durham University in 2005 for a thesis on thin film solar cells on a collaborative project with Bangor University. In 2005, I joined the photovoltaic group at Northumbria University to conduct research on photovoltaic solar cells based on CuInSe2 and related materials as part of the EPSRC funded project "SUPERGEN PV21 Photovoltaic Materials for the 21st Century". I joined the academic team of the Faculty of Engineering & Environment at Northumbria university in 2012.

I currently teach fundamental experimental skills in physics and engineering covering a broad range of concepts: laser diffraction, atomic spectroscopy, Hall effect and optical properties of semiconductors, and gravity to name a few. I also endeavour to demonstrate to students the role and value of error analysis in scientific measurements as well as practising key skills in the dissemination of scientific content.

My research background is in the area of thin film photovoltaics where layers 1 or 2 microns thick are used to absorb sun light and generate electricity. Despite half a century of tremendous progress the technology offers so much more and the prospects are very exciting. As an experimentalist I like spending my time whenever possible in the lab getting involved with the team in fabricating or characterising new layers and structures. Getting your first working device is always an event and I remember mine even though it was a long time ago.

Outside of work my spare time is spent exercising and I tend to train every day. I love cycling and swimming competing in short time trials. I used my scientific mind in data analysis of my cycling and training with graphs, tables and statistics to better my performance.
