Abstract

This research is dedicated to the improvement of the dielectric nanostructures decorated ultrathin crystalline silicon （c-Si） solar cells with broadband antireflection and enhanced absorption ability. Finite difference time domain （FDTD） method is used to simulate the effects of nanostructures with different sidewall profile on the broadband antireflection and enhanced absorption ability for the solar cells. Further analysis is implemented for the antireflection and light trapping mechanisms of the dielectric nanostructures decorated ultrathin c-Si solar cells with the help of the simulated field intensity distribution data. The results show that the dielectric nanostructures decorated c-Si solar cells presented improved light absorptance ability compared with the single antireflection layer （SARL） decorated cells, owing to the combination of multiple modes including Mie resonance scattering, Fabry-Perot resonance, ect., with the absorption even surpasses the Yablonovitch limit at some wavelengths range.
