Development of solar cell using single-walled carbon nanotube with perfect carbon network

制备了一种高结晶度单壁碳纳米管（SWCNT）薄膜/银电池。当可见光（650 nm）照射电池的swcnts /Ag界面时，产生0.16mV的光伏电动势。通过对光照射时电池的电流-电压（I-V）特性进行检测，曲线斜率呈现恒定的线性性质，发现SWCNT/Ag的界面为欧姆结。由于测量了光照射时电动势的爆发特性，电动势显示出松弛时间。我们发现光伏电动势是由光吸收转变为热的热电动势推导而来的。

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.
