Dr. James Connolly holds a PhD in design of models for compositionally graded quantum well solar cells and light trapping from Imperial College (1996), where he performed postdoctoral work developing analytical models of spectral response and efficiency of strained quantum well solar cells for thermophotovoltaics. In 2003, he was granted with a European Marie Curie fellowship in Paris (ENSCP - EDF) developing modelling and characterisation of chalcopyrite CIGS solar cells. He was continuously involved in the development of modeling of multi-junction III–V quantum-well solar cells with Imperial College London, London, U.K., from 1991 to 2009, including promising new concepts such as hot carrier effects, the demonstration of high efficiency and radiative dominance, and photon recycling in this radiative limit. He worked as a consultant for QuantaSol Ltd., helping to adapt the models that he has developed to the needs of the industrial design process. As of February 2009 he is Senior Researcher in charge of photovoltaic design and simulation with the Nanophotonic Technology Center, Polytechnic University of, Valencia, Spain. His current research interests include III-V on Si solar cells, plasmonics, and quantum-confined structures, and multiscale modeling for high efficiency 3rd generation photovoltaics.
