Abstract :
Oligoacene materials were applied as anode interfacial layers for small molecular organic photovoltaics. A sizeable enhancement in the short circuit current was observed which is attributed to an enhancement in the exciton diffusion efficiency. The application of tetracene anode interfacial layers to a synthesized ZnPc material yielded maximum power conversion efficiencies of 4.7%. Rubrene was also applied as an anode interfacial layer for devices of SubPc/C60 which showed a similar photocurrent enhancement.
