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.
