Enhanced light trapping in solar cells using snow globe coating.

Basch A, Beck F, Söderström T, Varlamov S, Catchpole KR - Prog Photovolt (2012)

Bottom Line: The coating is formed from high refractive index titania particles without containing binder and gives close to 100% reflectance for wavelengths above 400 nm.Snow globe coating is a physicochemical coating method executable in pH neutral media.The mild conditions of this process make this method applicable to many different types of solar cells.

Enhancement of the experimental EQE compared with the modelled data for (top) SG, (middle) paint 1 and (bottom) paint 2 coatings. Inset: modelled narrowed Lambertian, I Θ = cos[asin(nSi/neff ∗ sin Θ)], with neff = 1.4.

fig05: Enhancement of the experimental EQE compared with the modelled data for (top) SG, (middle) paint 1 and (bottom) paint 2 coatings. Inset: modelled narrowed Lambertian, I Θ = cos[asin(nSi/neff ∗ sin Θ)], with neff = 1.4.

Mentions: Figure 5 shows the modelled EQE spectra (dashed lines), compared with the experimentally measured data (solid lines). The modelled EQE spectra agree well with the experimental data for all three back reflectors. The inset in Figure 5 shows the angular distribution of the light scattered by the different coatings, all of which have an neff of 1.4. The inputs to the model and the resulting JSC enhancements (Λ) are summarised in Table II. It can be seen that the model also gives very good agreement with the experimental JSC enhancement.
