Modulated surface textures using zinc‐oxide films for solar cells applications

Abstract

Abstract We present modulated surface textures on glass substrates for improved light trapping in thin‐film silicon solar cells. The surface morphology, the roughness spectral distribution, and the scattering properties of the modulated surface‐textured substrates were characterized. We deposited solar cells on the modulated surface‐textured substrates and observed enhancement in the performance compared to a solar cell deposited on textured ZnO:Al (reference) substrates.
