- Abstract
- Organic photovoltaic (OPV) devices, which convert solar energy into electric power, have attracted attention because of their simple fabrication process, economical energy production, rapid improvement of performance, and possible flexibility. Organic polymer-based devices are industrialized and cost-effective owing to the solution-coating process, which can be applied to simple printing technology. However, the low-cost production technology for OPV will be useful when the efficiency of OPV is high. In order to enhance the efficiency of OPV at a low cost, we fabricated a hexagonal array nanopatterned (HANP) poly(3-hexylthiophene) and indene-C60 bisadduct blend that was used as an active layer by nanoimprint lithography. The J(sc) and conversion efficiency of HANP OPV were enhanced by 7.5% and 7.7%, respectively, compared with those of a reference device.
