This presentation will discuss quantitative methods for characterizing two-phase morphologies such as bulk heterojunctions for organic photovoltaics.   It will focus on the use of the well-known Porod law to determine the length of inhomogeneity and the interfacial area-to-volume ratio from grazing incidence small angle scattering patterns of thin films of polymer-fullerene blends used in organic solar cells. Extension of Porod's law to two dimensions, and its use to infer the actual dimensionality of nanoscale phase separation will also be described.
