Biographical Information

I'm a postdoctoral researcher in the Quantum Photovoltaics Group at Imperial College London. I'm interested in the fundamentals of solar energy conversion and how optical systems can be used to enhance efficiency and lower costs.

During my PhD I developed quantum dot based luminescent concentrators, and demonstrated the first quantum dot tandem collectors. I also developed an advanced optical ray tracing software, "PVTrace" (http://daniel.farrell.name/freebies/pvtrace) for simulation of luminescent photovoltaic devices. As a Research Associate I have developed rate models for both the hot-carrier solar cell and the intersubband cooling dynamics in quantum dots.
