According to a recent report by the US Department of Energy, “world demand for energy is projected to more than double by 2050 and to more than triple by the end of the century.” Thus, the development of alternative energy sources is now recognized by government, society and the global community as an urgent need. Plastic solar cells potentially can offer low cost, large area, flexible, light-weight, clean, and quiet alternative energy sources for indoor and outdoor applications. In this talk, I will give an overview of the current progress, challenges, and research opportunities in organic solar cells. Then, I will go over some recent results in our group. We have developed nanoscale characterization techniques to probe film morphology and interfaces in multilayer optoelectronic devices, to image the donor-acceptor networks laterally and vertically, to assign phase domains to the donor and the acceptor components, and to study nanoscale charge generation, transport and external quantum efficiency in polymer solar cells.
