Outline of Final Research Achievements

Positive-type single-walled carbon nanotube (SWCNT) with carboxyl groups and negative-type SWCNT with doped nitrogen atoms were synthesized in this study. In an effort to fabricate efficient near-infrared solar cells with combination of thermoelectromotive force and photovoltaic effect, p-SWCNT/n-SWCNT thin film solar cells with pn junction were produced and their performance were investigated. The p-SWCNT/n-SWCNT thin film solar cells had no photovoltaic force. One of the reasons was considered to be due to no formation of pn junction.
