Electronic materials and interfaces

My group works on furthering the fundamental understanding of a range of electronic materials and their interfaces with other materials or the environment. Much of our work has focussed on the advancing silicon materials for photovoltaic solar cells, but we also have interests in lithium-ion batteries, wide bandgap materials for power electronics, and thermoelectrics.

Advanced silicon photovoltaics

Photovoltaics have the potential to supply the majority of the world’s electricity. Today’s market is dominated from cells made from bulk silicon (~90%) and silicon’s abundance and properties (chemical stability, density, band gap, and non-toxicity) mean that there is a good chance it will continue to dominate in the longer term. Although uptake of photovoltaic technologies is increasing rapidly, without subsidy all stable photovoltaic technologies are too expensive to compete with incumbent electricity generation sources. Dr John Murphy moved his research activity to Warwick from Oxford in February 2013. His group aims to improve the cost-effectiveness of silicon photovoltaics by: (i) improving the performance of existing materials; and (ii) facilitating the use of cheaper (less pure) feedstocks.
