Abstract

A high light scattering morphology on glass used as a substrate for thin film solar cells was fabricated using spherical silica particles and spin-on-glass. After deposition of Al-doped ZnO thin films, a hemispherical morphology appeared at the surface, and a high haze value of 77% (λ = 900 nm) was obtained when the cover ratio of the silica particle was 44%. The quantum efficiency of microcrystalline thin film Si solar cells was improved at wavelengths over 700 nm due to the textured morphology formed by the silica particles and spin-on-glass.
