Resonant dielectric structures are a promising platform for addressing the key challenge of light trapping in thin-film solar cells. Grandidier et al. (pp. 255—260) experimentally and theoretically demonstrate efficiency enhancements in solar cells from dielectric nanosphere arrays. Two distinct amorphous silicon photovoltaic architectures were improved using this versatile light-trapping platform. In one structure, the colloidal monolayer couples light into the absorber in the near-field acting as a photonic crystal light-trapping element. In the other, it acts in the far-field as a graded index antireflection coating to further improve a cell which already included a state-of-the-art random light-trapping texture to achieve a conversion efficiency over 11%.

A novel approach to increasing light absorption in thin-film solar cells is demonstrated by Jonathan Grandidier and co-workers on p. 1272. This new method involves redirecting the incident sunlight into the cell via coupling to the whispering gallery modes of dielectric spheres, which lie atop the cell. Such a scheme leads to a predicted current enhancement of >12% for a-Si.
