Outline of Final Research Achievements

The range of use of carbon nanotubes in organic solar cells has been further expanded. We functionalized carbon nanotubes with fullerene derivatives and lithium-ion-encapsulated fullerenes to produce perovskite solar cells with energy conversion efficiencies exceeding 20%. For the first time, a film of double-walled carbon nanotubes could be used as a transparent electrode for solar cells. We also succeeded in applying metal carbon nanotubes to silicon photovoltaic solar cells instead of conventional metal electrodes by using Nafion as a dopant.

Academic Significance and Societal Importance of the Research Achievements

カーボンナノチューブ薄膜を透明電極，あるいは金属電極の代わりの裏面電極とすることで，将来的に金属の使用をより低減した有機系太陽電池が構築できる．インジウムスズ酸化物透明電極や金・銀などの裏面電極は高価であり，有機系太陽電池のコストの半分程度を占めるが，この電極部分をカーボンナノチューブで置き換えることにより，コスト優位性が高い太陽電池が実現する．
