| Outline of Research at the Start |
I propose replacing the carbon-paste by carbon nanotubes in the mesoporous perovskite system. The aerosol-synthesised carbon nanotube films are a better choice than the carbon-paste as they are low-temperature processable and has intrinsic charge selective ability, which translate to higher efficiency. In order to enhance the efficiency and stability even further, I plan to apply a novel Li@C60TFSI dopant-added hole-transporting materials which can function as antioxidants for the devices.

| 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．
