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.

fig04: Experimental reflection of SG coating (solid line), paint 1 (dotted line) and paint 2 (dotted line).

Mentions: The reflectance results are shown in Figure 4. SG coating has close to 100% reflectance at wavelengths above 400 nm. The novel coating is more reflective than both types of paint because of index contrast between the air and the TiO2 particles in the SG coating. The coating of paint 2 was opaque, so the loss through transmission is negligible, but there is some loss in reflectance probably attributable to absorption in the binder. For paint 1, absorption in the paint binder and transmission through the paint lower the reflection further.
