In this paper, we study the efficiency of several types all-dielectric, non-resonant, antireflection, and light-trapping coatings for enhancement photovoltaic absorption in thin-film silicon solar cells. We compare offered by a square array nano-pillar shaped voids dielectric covering cell with that granted flat blooming layer, densely packed nanospheres. optimize these show newly proposed nanostructure allows significant increase absorption. The dependence antireflection properties on angle incidence is numerically investigated, it shown keeps optimal also after averaging over angles.
