Outline of Final Research Achievements

The purpose of this work is to fabricate semitransparent organic solar cells utilizing single-wall carbon nanotube (SWCNT) film, which is one of the nano-carbon materials, as top electrode. During the first year, as a preliminary experiment, we used oxide/thin metal/oxide multilayer structure for the transparent top electrode and succeeded in fabricating semitransparent organic solar cells using semiconducting polymer and fullerene derivative as an active layer. During the second year, based on the fabrication conditions, we carried out a fabrication of semitransparent organic solar cells using SWCNT top electrode. We developed simple method in a way that the active layer on ITO/glass substrate and SWCNT film on PET substrate were laminated together by pressing. As a result, the new semitransparent organic solar cell using SWCNT electrode was successfully fabricated.
