  • Interfaces of organic donor-acceptor blends provide intermolecular charge-transfer states with red-shifted but weak absorption. By introducing an optical micro-cavity; Siegmundet al., enhance their photoresponse to achieve narrowband NIR photodetection with broad spectral tunability.

  • The conversion efficiency of organic solar cells suffers from their low open-circuit voltages. Here, the authors expose a link between electron-vibrations coupling and non-radiative recombinations, derive a new limit for the efficiency of organic solar cells, and redefine their optimal optical gap.
