Research Abstract |
Organic solar cells have attracted attention as a cheap solar cell instead of Si-based ones. But the high resistance of organic materials is a problem to get a high efficiency. The purpose of this research is the improvement of organic solar cell by using a highly conducting carbon nanotube as a core. It was found that the short circuit current of TiO_2-based solar cell is increased by the increase of amount of adsorbed dye, resulting in the improvement of solar cell efficiency. The solar cell efficiency was degraded by introducing carbon nanotube in the active layer with bulk heterojunction, but was increased by adding carbon nanotube in the hole transporting layer or layer-structure organic solar cell.
