A nanostructured antireflection coating has been fabricated on glass side of an indium tin oxide (ITO) coated glass by self-assembling a monolayer of nano-silica spheres. Significant reduction in the weighted reflectance from 10.2% to 7.2% at 5° incident angle is observed. At 60° incident angle, the weighted reflectance of ITO glass with antireflection coating is still about 3% lower than that of bare ITO glass. This nanostructured antireflection coating has been applied on the glass surface of the ITO substrate in a polymer photovoltaic cell. Improvement in the power conversion efficiency from 1.80% to 2.05% at normal incidence has been demonstrated. The relative enhancement in the conversion efficiency is almost independent of the incident angles.
