我们描述了使用单壁碳纳米管（SWNT）薄膜作为透明和导电电极的空穴收集在聚（己基）噻吩-[6-6]苯基-C-61-丁酸甲酯（P3 HT-PCBM）的有机光致发光。我们报告称，在空气中测量的100 mW/cm（2）多色白色光照明下，功率转换效率为1%，填充因子为0.3，短路电流为6.5 mA/cm（2）。这些值相对高于在氧化铟锡（ITO）玻璃基板上制成的类似厚度的参考电池。这是由于单壁碳纳米管和P3 HT-PCBM纳米复合材料之间的界面的三维性质。我们的研究结果表明，溶液处理的单壁碳纳米管薄膜是一个可行的替代ITO的光伏器件，消除了昂贵的真空沉积步骤中的有机太阳能电池的制造。(C)2005年美国物理学会。
We describe the use of single-wall carbon nanotube (SWNT) thin films as transparent and conducting electrodes for hole collection in poly(hexyl)thiophene-[6-6]phenyl-C-61-butyric acid methyl ester (P3HT-PCBM) organic photovoltaics. We report a power conversion efficiency of 1%, with a fill factor of 0.3 and a short-circuit current of 6.5 mA/cm(2) under 100 mW/cm(2) polychromatic white light illumination measured in air. These values are comparatively higher than reference cells of similar thickness made on indium tin oxide (ITO) glass substrates. This is attributed to the three-dimensional nature of the interface between the SWNTs and the P3HT-PCBM nanocomposite. Our results indicate that solution processed SWNT thin films are a viable alternative to ITO for photovoltaic devices, eliminating an expensive vacuum deposition step in the fabrication of organic solar cells.
