Abstract.  Our present work proposes a systematic geometric model comprising vertical dual silver nanostrips placed on the top of a thin-film amorphous silicon solar cell. In the first layer, cylindrical silver nanostrips are embedded in the antireflection coating and the other one is placed just above it. Combining the two improves the absorption over the wide spectral range. A finite-difference time domain technique has been used to confirm that a vertical dual silver nanostructure improves absorption over a broad spectrum in comparison to a single layer. Size, shape, and interspacing of the nanostructures have been tuned to obtain the preeminent results. This optimized geometry gives a total quantum efficiency of 32.02% under AM1.5G.
