Abstract

See full text

Embodiments relate to a thin film solar cell backside contact. A planar substrate is provided and an associated backside of the substrate is modified to form one or more pedestals. The modified substrate is layered with multiple layers of material, including a conducting layer, a reflective layer, and a passivation layer. The layered backside substrate is polished to expose portions of the conducting layer at discrete locations on the backside of the substrate. The exposed portions of the conducting layer maintain direct electrical communication between an absorber layer deposited on the layered backside substrate and the conducting layer.
