Triplet escitons at the nnthracene crystal surface yielded a hole photocurrent which was diffusion controlled concerning the excitons at high concentration of the oxidant. Similarities were found in hole photocurrents involving directly excited triplet excitons and in methylene blue sensitized ones.
The photoconductivity of films of amorphous molecular semiconductors increases upon simultaneous photogeneration of singlet electron-hole pairs (EHPs) and triplet excitons and decreases upon photogeneration of triplet EHPs and triplet excitons. An increase in external electric field strength leads t
