摘要/Abstract

摘要： 利用聚苯乙烯胶体球自组装技术和纳米压印技术在单晶硅表面构筑了两种周期性微结构. 反射光谱表明, 两种周期性微结构都能够对特定波长的入射光有一定的减反射效果; 表面光电压谱和吸收光谱相对应, 在具有减反射效果的波长范围内观察到了表面光电压增强的现象, 说明这种表面构筑微结构的技术可以有效地利用在单晶硅太阳能电池的制造和设计上, 从而提高单晶硅太阳能电池的光电转换效率. 对这种周期性微结构的减反射机理进行了初步探讨.

Abstract: Two different microstructures were constructed on the single crystalline silicon surface which was used as antireflection coatings. The reflection spectra show that these period microstructures have an antireflection effect in some regions of the spectrum. The surface photovoltaic spectra show a corresponding photovoltaic enhancement in these spectrum regions. The antireflection mechanism was also discussed. This antireflection coating technique can be used to product and design the single crystalline silicon solar cells for high photoelectric conversion efficiency.

Key words: Single crystalline silicon, Microstructure, Antireflection, Photovoltaic property
