提出了单纳米线太阳能电池器件效率测量的基本限制。我们评估了基底、光偏振和米氏共振的存在对直径为 10 至 300 nm 的纳米线吸收太阳光谱的影响。我们发现，在这种配置下测得的效率可能会被低估，GaAs 纳米线的效率可被低估 1.6 至 7.0 倍，硅纳米线的效率可被低估 6.7 至 15.9 倍。这些结果为理解单纳米线器件的测量极限提供了参考。 (C) 2011 年美国物理研究所。 [doi:10.1063/1.3672168]
The fundamental limits for the measurement of the efficiency of single nanowire solar cell devices are presented. We evaluate the effect of the substrate, light polarization, and existence of Mie resonances in the absorption of the solar spectrum for nanowires with diameters from 10 to 300 nm. We find that the efficiency measured under such configuration can be underestimated between a factor 1.6 and 7.0 for GaAs nanowires and between 6.7 and 15.9 for silicon nanowires. These results constitute a reference for understanding the limits in the measurement of single nanowire devices. (C) 2011 American Institute of Physics. [doi:10.1063/1.3672168]
