Lewis studied for a BSc in Physics from Loughborough University, where he stayed to do his PhD with the Centre for Renewable Energy Systems Technology.
Project
Pyrolysis of solution-processed CZTS for upscale
Current methods for making solar panels are either expensive, slow, energy intensive, toxic, or every combination of all four. Lewis' project is about producing CZTS (copper, zinc, tin and sulfur) solar cells by simply spraying a mixed solution onto a substrate. All four elements are common in the Earth's crust which makes them cheap, they have low toxicity, and a spraying technique would mean it is scalable for industry. The ultimate aim is to bring inexpensive photovoltaics to the masses.
