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: A novel method, snow globe coating, is found to show significant enhancement of the short circuit current JSC (35%) when applied as a scattering back reflector for polycrystalline silicon thin-film solar cells.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.

Snow globe (SG) coating method: (a) dispersed titania particles form a binder free coating (SG coating) after settling by gravity. Scanning electron micrograph of titania particles, (b) scale bar is 10 µm; (c) scale bar is 200 nm.

fig01: Snow globe (SG) coating method: (a) dispersed titania particles form a binder free coating (SG coating) after settling by gravity. Scanning electron micrograph of titania particles, (b) scale bar is 10 µm; (c) scale bar is 200 nm.

Mentions: The SG coating method (see Figure 1) uses the fact that thick, uniform coatings of relatively large particles can be achieved by dispersion followed by settling by gravity, as in a children's snow globe. The technique allows large particles, which provide highly effective light scattering to be used. For the SG coating, titania particles without binder were used.
