Outline of Final Research Achievements |
The problem on organic photovoltaic solar cells (OPV) is low power conversion efficiency (PCE). PCE is about 5% in mainstream bulk-hetero junction type OPV devices. The bulk-hetero junction forms nanostructure by annealing. The phase separations by annealing depend on inherent nature of molecules. Therefore, precise control of nano domain size is difficult. In this respect, we tried fabrication of columnar-like structure by simple technique such as liquid-liquid interfacial assembly technique using fullerene nanocrystals. By using this technique, we try to precise control of nanostructure in OPV. Fabricated OPV structure is invested structure and their PCE is about 3 %.
