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.Keywords: Back reflectors; Coating methods; High refractive index; Light-trapping; Neutral media; Thin-film solar cells; Titania; Dielectric materials; Polysilicon; Reflection; Refractive index; Semiconductor materials; Snow; Solar cells; Thin films; Titanium dioxi dielectric materials; light trapping; refractive index; semiconductors; thin films; zeta-potential201210.1002/pip.22402016-02-24
