A series of (n–i–p) a‐Si:H solar cells with light‐trapping by front‐side plasmonic Ag nanoparticle arrays was compared to a reference without the plasmonic arrays as well as to a benchmark with a conventional textured back‐side reflector for light‐trapping. The external quantum efficiency of the solar cells was determined experimentally by spectral response measurements. The comparison gives a comprehensive snap‐shot of the potential of front‐side plasmonic light‐trapping in a‐Si:H solar cells for the array parameterization used in this study. Relative to the reference the plasmonic arrays lead to clearly enhanced light‐trapping in the longer wavelength range (600–800 nm). This enhancement is lower than the one achieved by the benchmark though, which is discussed in terms of further research perspectives.
