Research Abstract |
The organic photovoltaic devices(OPVs) with nanostructured interfaces were successfully fabricated. However, the expected effect of the nanostructured interface could not be observed probably due to the insufficiency of the pattern size. The observed performance of photoelectrical conversions of nanostructured OPVs were almost same as that of normal flat type OPVs. This result indicates that the device performance of the P3HT : PCBM system is insensitive to the interface structure between active layer and top electrode, which is important for future low-cost and large-area fabrication of the OPVs. Our studies also suggest the unique property of the nanostructured electrode with which carrier collection through a thick buffer layer is possible.
