Design of nanostructures for photoelectric conversion using an organic vertical superlattice

摘要

The intentional design to the 2.5 nm scale based on a concept for the design of nanoscopic structures via film thickness control was demonstrated. We fabricated sandwich-type cells incorporating organic vertical superlattices by using a microtome and proved that structural design below the 10 nm scale is necessary in order to realize solid-state organic solar cells. The present technique can be applied to the fabrication of novel optoelectronic devices with designed nanostructures that are composed of any kind of material.
