Abstract
Surface texturing of the transparent conductive oxide (TCO) front contact of a thin film photovoltaic (TFPV) solar cell is needed to enhance the light-trapping capability of the TFPV solar cells and thus improving the solar cell efficiency. Embodiments of the current invention describe chemical formulations and methods for the wet etching of the TCO. The formulations and methods may be optimized to tune the surface texturing of the TCO as desired.
