Professor Guillaume Zoppi

My research background is in the area of thin film photovoltaics where layers one or two 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.
