开发纳米结是制造光伏的一种普遍而有效的方法。我们报道了一种肖特基结太阳能电池，它是在单独的CdSe纳米带上涂覆碳纳米管薄膜，在AM 1.5g，100 mW/cm(2)的光照条件下，开路电压为0.5~0.6V，功率转换效率为0.45~0.72%。在我们的平面器件结构中，CdSe纳米带作为一个平坦的衬底来维持纳米管的网络，而纳米管薄膜在它们的界面处与下面的纳米带形成Shottky结，也为器件制造了一个透明电极。纳米带上的纳米管太阳能电池可以在前(纳米管侧)或后(纳米带侧)照明下工作，在空气中性能稳定。我们的结果表明，基于碳纳米管薄膜和半导体纳米结构的大面积太阳能电池是一种很有前途的方法。
Developing nanostructure junctions is a general and effective way for making photovoltaics. We report Schottky junction solar cells by coating carbon nanotube films on individual CdSe nanobelts with open-circuit voltages of 0.5 to 0.6 V and modest power-conversion efficiencies (0.45-0.72%) under AM 1.5G, 100 mW/cm(2) light condition. In our planar device structure, the CdSe nanobelt serves as a flat substrate to sustain a network of nanotubes, while the nanotube film forms Shottky junction with the underlying nanobelt at their interface and also makes a transparent electrode for the device. The nanotube-on-nanobelt solar cells can work either in front (nanotube side) or back (nanobelt side) illumination with stable performance in air. Our results demonstrate a promising way to develop large-area solar cells based on thin films of carbon nanotubes and semiconducting nanostructures.
