When: Friday February 25 at 11:00 AM (Just for this week, 30 min before the usual).
Where: Mallinckrodt 217
What: Jacob Krich will give a talk on:

"Recombination in intermediate band photovoltaics.

Intermediate band photovoltaics (IBPV) hold the promise of radical improvements in photovoltaic efficiency. I will discuss the design principles of IBPV and the tradeoffs to be made with different choices of energy gaps.  Full realization of IBPV's potential requires a device with a sufficiently low  recombination rate. I will discuss the factors important for recombination and connect the theory of multiphonon recombination to Marcus theory.  I will present updated results from the scaling studies of localization in a topologically disordered system, which I presented last summer, along with new results on estimating recombination rates without intense computational effort."
