Harvesting the Full Potential of Photons with Organic Solar Cells

Harvesting the Full Potential of Photons with Organic Solar Cells

A low‐bandgap polymer:fullerene blend that has significantly reduced energetic losses from photon absorption to VOC is described. The charge‐transfer state and polymer singlet are of nearly equal energy, yet the short‐circuit current still reaches 14 mA cm−2.
