Thin substrate photovoltaic and methods for making them are disclosed herein. In an embodiment, a photovoltaic device may include a substrate comprising a semiconductor material, one or more core structures, each extending essentially perpendicularly from a first surface of the substrate such that the core structures and the substrate form a single crystal, a shell layer disposed at least on a portion of a sidewall of the core structures and on the first surface, and a conductive layer disposed between adjacent core structures. The conductive layer forms an ohmic contact with the shell layer disposed on the first surface and between the adjacent core structures. |
