摘要： In aspects of the present invention, a method is disclosed to form a lamina having opposing first and second surfaces. Heavily doped contact regions extend from the first surface to the second surface. Generally the lamina is formed by affixing a semiconductor donor body to a receiver element, then cleaving the lamina from the semiconductor donor body wherein the lamina remains affixed to the receiver element. In the present invention, the heavily doped contact regions are formed by doping the semiconductor donor body before cleaving of the lamina. A photovoltaic cell comprising the lamina is then fabricated. By forming the heavily doped contact regions before bonding to the receiver element and cleaving, post-bonding high-temperature steps can be avoided, which may be advantageous.

摘要： A semiconductor assembly is described in which a support element is constructed on a surface of a semiconductor lamina. Following formation of the thin lamina, which may have a thickness about 50 microns or less, the support element is formed, for example by plating, or by application of a precursor and curing in situ, resulting in a support element which may be, for example, metal, ceramic, polymer, etc. This is in contrast to pre-formed support element which is affixed to the lamina following its formation, or to a donor wafer from which the lamina is subsequently cleaved.Fabricating the support element in situ may avoid the use of adhesives to attach the lamina to a permanent support element. In some embodiments, this process flow allows the lamina to be annealed at high temperature, then to have an amorphous silicon layer formed on each face of the lamina following that anneal.

摘要： Fabrication of a photovoltaic cell comprising a thin semiconductor lamina may require additional processing after the semiconductor lamina is bonded to a receiver. To minimize high-temperature steps after bonding, the p-n junction is formed at the back of the cell, at the bonded surface. In some embodiments, the front surface of the semiconductor lamina is not doped or is locally doped using low-temperature methods. The base resistivity of the photovoltaic cell may be reduced, allowing a front surface field to be reduced or omitted.

摘要： A photovoltaic cell is described having emitter portions formed at both a light-facing surface and a back surface of the cell. In some embodiments, heavily doped emitter regions extend between the front and back emitter regions, connecting them electrically. Use of this structure is particularly well-adapted to a cell formed by implanting a semiconductor donor body with hydrogen and/or helium ions, affixing the donor body to a receiver element, cleaving a lamina from the donor body, and completing fabrication of a photovoltaic cell comprising the lamina. The emitter portion formed at the unbonded surface may comprise amorphous silicon. The lamina may be thin, for example 10 microns thick or less.
