Abstract

Embodiments of the invention generally provide a high efficiency solar cell using a novel processing sequence to form a solar cell device. In one embodiment, the methods include forming one or more layers on a backside of a solar cell substrate prior to the texturing process to prevent attack of the backside surface of the substrate. In one embodiment, the one or more layers are a metalized backside contact structure that is formed on the backside of the solar cell substrate. In another embodiment, the one or more layers are a chemical resistant dielectric layer that is formed over the backside of the solar cell substrate.
