Quantum dot enabled photovoltaic cells

We combine fundamental studies of the photophysics of semiconductor quantum dots adsorbed on surfaces with realizations of new designs for third-generation photovoltaic cells incorporating quantum dots.

We have introduced several new designs for a hybrid quantum-dot - dye sensitized cells. Properly designed quantum dots have also been shown to photoinduce a dipole, leading to modification of the band alignment in sensitized cells. More recently, we have begun working with methylammonium and cesium lead halide perovskite materials and their hybrids with colloidal semiconductor nanocrystals for photovoltaic applications.
