Revealing the Full Charge Transfer State Absorption Spectrum of Organic Solar Cells

Anisotropic charge transfer (CT) state absorption originating from the natural transition dipole alignment at planar donor–acceptor interfaces can be exploited to reveal the full CT state absorption spectrum in organic solar cells. Application of this method reveals the existence of previously unobs...

Zusammenfassung:Anisotropic charge transfer (CT) state absorption originating from the natural transition dipole alignment at planar donor–acceptor interfaces can be exploited to reveal the full CT state absorption spectrum in organic solar cells. Application of this method reveals the existence of previously unobserved, higher‐lying CT absorption buried beneath the excitonic background.
