A method for fabricating a solar cell and the and the resulting structures, e.g., micro-electronic devices, semiconductor substrates and/or solar cells, are described. The method can include providinga solar cell having metal foil having first regions that are electrically connected to semiconductor regions on a substrate at a plurality of conductive contact structures, and second regions; locating a carrier sheet over the second regions; bonding the carrier sheet to the second regions; and removing the carrier sheet from the substrate to selectively remove the second regions of the metal foil. 本公开描述了一种用于制造太阳能电池的方法及所得到的结构，例如微电子装置、半导体基板和/或太阳能电池。所述方法可包括：提供具有金属箔的太阳能电池，所述金属箔具有第一区域和第二区域，所述第一区域在多个导电接触结构处电连接至基板上的半导体区；将载体片材定位在所述第二区域上方；将所述载体片材结合至所述第二区域；以及从所述基板去除所述载体片材以选择性地去除所述金属箔的所述第二区域。
