Grazing-Incidence Wide-Angle X-Ray Scattering (IMAGE)
Caption
Organic solar cells are steadily improving as new materials are developed for the active layer, and a paper published this week in Applied Physics Reviews presents a practical guide for selecting materials for ternary organic solar cells. The authors set out to employ component engineering to extend the light absorption and efficiency of solar cells in a simple, physical way instead of the complicated process of synthesizing new semiconductors. Grazing-incidence wide-angle X-ray scattering was used to profile the molecular packing and orientation of the binary system's material with PBDB-T-SF and IT-4F added in different amounts.
