Abstract:	A scalable procedure for nano-patterning the bulk heterojunction layer in organic photovoltaic (OPV) devices is reported. Nano-patterning is shown to increase light absorption in poly(3-hexylthiophene) : [6,6]-phenyl-C61-butyric acid methyl ester (P3HT : PCBM) devices (ITO\WO3\P3HT : PCBM\Ca\Al). Nano-patterning also modifies electric fields in OPV devices, thus affecting charge harvesting. Nano-patterned OPV devices with a power conversion efficiency of 4% are presented. Comparable efficiencies are also obtained by optimization of thicknesses in a flat-layer device. Trade-offs between absorption enhancement and charge harvesting deterioration induced by nano-patterning are discussed as well as possible optimization strategies.
