Quasi-Steady-State Measurement of Exciton Diffusion Lengths in Organic Semiconductors
TL;DR: Pulsed-PLQY was used to evaluate the diffusion length in a variety of technologically relevant organic semiconductors and found that the diffusion lengths in NFA's are much larger than in the benchmark fullerene and that this increase is driven by an increase in diffusivity as discussed by the authors .
