We report the broadband and omnidirectional antireflection study of a high aspect ratio porous nano-network on the glass substrate fabricated using the combination of candle soot coating as a sacrificial layer and HF-based vapor phase etching method. Field emission electron microscopy results showed that the pores have the tapering profile, and the pores size was restricted to the sub-wavelength dimension. Therefore, an excellent broadband and omnidirectional antireflection with an enhancement of ~7% in the maximum transmittance as compared to plain glass has been achieved. Moreover, reflectance from the etched surface exhibited very low sensitivity to state of polarization and it remains quite low (<1.5%) for both s-and p-polarization over a broad range of incident angles up to 40o. The broadband antireflection property was further examined by finite difference time domain simulation. Further, we demonstrate a relative improvement of ~6% in the Isc (Isc/ Isc) of solar cell encapsulated with the etched glass.
