Photoenhanced Conductivity in Organic Crystals

Abstract Macrotrap model for charge carrier trapping is applied to describe photo-enhanced currents in anthracene-Like crystals. The currents are due to the interaction between triplet excitons and charge carriers trapped in spatially extended trapping domains (macrotraps). The model allows to selfconsistency explain experimental voltage and light intensity dependences of the photo-enhanced conductivity measured in anthracene crystals.
