Research Fellow

Nanoscale Spectroscopy Laboratory

The current roll-out of photovoltaics is transforming our energy infrastructure, but classical photovoltaics have fundamental limitations on their efficiency. Laszlo is discovering new scattering processes that work around these limitations to generate more excitons, with the aim of improving access to energy while protecting the environment.
