Construction and testing of third generation photovoltaics

We do fundamental materials chemistry research on photovoltaics, materials that convert sunlight to electricity, aiming to improve the efficiency of cells constructed from low-cost materials that can be applied to large-area surfaces.  The two major projects are 

  • dye-sensitized solar cells incorporating zinc oxide nanotube and nanosheet photoanodes; and
  • heterojunction cells produced by spraying or printing colloidal suspensions of quantum dots

There is a wide array of activities in our lab, including solid-state synthesis, cell construction, and materials characterization. We use tools as diverse as absorption and fluorescence spectroscopy, scanning electron microscopy, atomic force microscopy, current-voltage curve analysis, and various forms of impedance spectroscopy to characterize our devices.
