Ternary Acceptor and Donor Materials Increase Photon Harvesting in Organic Solar Cells

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.
