Combined plasmonic and dielectric rear reflectors for enhanced photocurrent in solar cells

Basch, A.; Beck, Fiona; Söderström, T.; Varlamov, S.; Catchpole, Kylie


A doubling of the photocurrent due to light trapping is demonstrated by the combination of silvernanoparticles with a highly reflective back scatterer fabricated by Snow Globe Coating on the rear of a 2 μm polycrystalline silicon thin film solar cell. The binder free high refractive index titania particles can overcome light losses due to transmission. Modelling indicates that adding plasmonicnanoparticles to the back scatterer widens the angular distribution of scattered light such that over...[Show more]
