Nanotexturing of silicon solar cells using acids

Abstract

Isotropic texturing of silicon is among the key issues in solar cell fabrication. Attempts have been made using mechanical, plasma and other techniques [1–3]. This work reports a study on the possibility of applying acidic texturing using in the texturing of crystalline silicon solar cell. Alkaline texturing is widely used in solar cell processing, to lower the reflectance of the cell surface.
