Abstract

Composition maps, shown within a photovoltaic device, are generated from energy-filtered transmission electron microscopy images to map out the compositional heterogeneities in the active layer of polymer/fullerene solar cells with nanometer resolution. As reported by Enrique D. Gomez and coworkers in article number 1400116, these images help elucidate the complex relationship between the microstructure of the active layer and the performance of organic photovoltaic devices.
