| Research Abstract |
A high crystallinity single-walled carbon nanotube (SWCNT) film/Ag cell was fabricated. When the SWCNT/Ag interface of the cell was irradiated with a visible light (650 nm), photovoltaic electromotive force of 0.16mV occurred. After checking the current-voltage (I-V) characteristic of the cell at the time of the light irradiation, the slope of the curve showed the constant linear nature, and the interface of SWCNT/Ag was found to be ohmic junction. As a result of having measured the electromotive force outbreak properties for the on/off of light irradiation, the electromotive force showed relaxation time. We found that the photovoltaic electromotive force was derived from thermoelectromotive force by light absorption having changed for heat.
