Photovoltaic (PV) devices have undergone a remarkable expansion, with growth rates of over 40% per year for over 10 years, to the point where the photovoltaic market now uses more silicon than the IC industry and is larger than the LED market1. This growth and the reductions in cost have been largely driven by economies of scale and process optimization, rather then extensive technology innovations, and the todays solar cells retains many similarities to those of a decade ago. Further development of PV requires new approaches. A commonality among new photovoltaic technologies is the prevalence of interfaces between ordered material (either bulk or nanostructures such as quantum dots) and a material with no long range order, such as organic solutions, TiO2 or amorphous semiconductors. In many devices, interfaces between two such materials control the performance of the solar cell. A necessary scientific advance in developing new solar cells is the ability to understand and simulate transport and recombination occurring at and across such interfaces and materials.
