Title: | Diffusion-enhanced exciton dissociation in single-material organic solar cells | Authors: | Hoang, Nong, V Nikolis, Vasileios C. Baisinger, Lukasz VANDEWAL, Koen Pshenichnikov, Maxim S. |
Issue Date: | 2021 | Publisher: | ROYAL SOC CHEMISTRY | Source: | PCCP. Physical chemistry chemical physics (Print), 23 (37) , p. 20848 -20853 | Abstract: | Single-material organic solar cells have recently attracted research attention due to their simplicity, morphological robustness and high yield of exciton dissociation. Using alpha-sexithiophene as a model system, we show that the single-event probability of the exciton dissociation at the boundaries of polycrystalline domains with different molecular orientation is extremely low (similar to 0.5%), while a high efficiency of charge generation is gained via hundred-fold crossings of the domain boundaries due to the long exciton diffusion length (similar to 45 nm). | Notes: | Pshenichnikov, MS (corresponding author), Univ Groningen, Zernike Inst Adv Mat, Nijenbargh 4, NL-9747 AG Groningen, Netherlands. m.s.pchenitchnikov@rug.nl |
