| Research Abstract |
In this study, we prepared high crystalline single-walled carbon nanotube (SWCNT) thin film (transmittance 9.0 %)/bulk film (transmittance 2.3 %) interfacial structured film cells and investigated the photoelectromotive force. When a light (solar simulator AM1.5 with 100 mW/cm2) was irradiated toward the bulk film side (10×10 mm2) of the cells, the photoelectromotive force of 0.90 mV occurred. The Seebeck coefficient was estimated to be +66.4 μV/K, and the carrier of high crystalline SWCNT was a positive hole. Additionally, the interface of thin/bulk film was not Schottky junction but Ohmic since the I-V curve of the cells showed a liner shape. The photoelectromotive force in the SWCNT film/bulk interface cell is considered to be thermoelectromotive force derived from thermal gradient generated by photo-excitation electron converted into heat.
