On illumination, the excitons generated within the exdton diffusion length from the donor-acceptor interface can reach the interface within their respective exdton lifetime, where charge separation is favorable when the following condition is fulfilled ... [Pg.389]

For an organic semiconductor blend with an average dielectric constant of 3, this Coulomb capture radius is 19 nm at room temperature, which is somewhat larger than the typical exdton diffusion length of 10 nm. Of course for this estimation it... [Pg.134]

The surface-enhanced exdton dissodation model is based on the assumption that the photogenerated exdton diffuses to the photoconductor surface. Then due to the interaction with a donor or an acceptor surface center, the exdton dissociates... [Pg.849]

In the case of thick samples, when the thickness is larger than the absorption depth and the exdton diffusion length Uexc = (DacZacY the photogeneration effidency is directly proportional to the absorption coeffident ... [Pg.849]
