Abstract: A novel method is described to create low-relief texture at a light-facing surface or a back surface of a photovoltaic cell. The peak-to-valley height and average peak-to-peak distance of the textured surface is less than about 1 microns, for example less than about 0.8 micron, for example about 0.5 microns or less. In a completed photovoltaic device, average reflectance for light having wavelength between 375 and 1010 nm at a light-facing surface with this texture is 6 percent or less, for example about 5 percent or less, in some instances about 3.5 percent. This texture is produced by forming an optional oxide layer at the surface, lightly buffing the surface, and etching with a crystallographically selective etch. Excellent texture may be produced by etching for as little as twelve minutes or less. Very little silicon, for example about 0.3 mg/cm2 or less, is lost at the textured surface during this etch.

Abstract: Fabrication of a photovoltaic cell comprising a thin semiconductor lamina may require additional processing after the semiconductor lamina is bonded to a receiver.

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.

Abstract: Methods and devices are provided for high-throughput printing of semiconductor precursor layer from microflake particles. In one embodiment, the method comprises of transforming non-planar or planar precursor materials in an appropriate vehicle under the appropriate conditions to create dispersions of planar particles with stoichiometric ratios of elements equal to that of the feedstock or precursor materials, even after settling. In particular, planar particles disperse more easily, form much denser coatings (or form coatings with more interparticle contact area), and anneal into fused, dense films at a lower temperature and/or time than their counterparts made from spherical nanoparticles. These planar particles may be microflakes that have a high aspect ratio. The resulting dense film formed from microflakes is particularly useful in forming photovoltaic devices.

The method is used for controlling the uniformity of a ribbon beam.

Abstract: An ion implanter has an implant wheel with a plurality of wafer carriers distributed about a periphery of the wheel. Each wafer carrier has a heat sink for removing heat from a wafer on the carrier during the implant process by thermal contact between the wafer and the heat sink.

The lift structure is operated to move between the first and second positions wheel the implant is rotating. This allows control of wafer temperature during the implant process by adjusting the thermal contact between wafers and heat sinks.

Abstract: Nanostructured layers with 10 nm to 50 nm pores spaced 10-50 nm apart, a method for making such nanostructured layers, optoelectronic devices having such nanostructured layers and uses for such nanostructured layers are disclosed. The nanostructured layer can be formed using precursor sol, which generally includes one or more covalent metal complexes, one or more surfactants, a solvent, one or more optional condensation inhibitors, and (optionally) water. Evaporating the solvent from the precursor sol forms a surfactant-templated film. Covalently crosslinking the surfactant-templated film forms a nanostructured porous layer. Pore size is controlled, e.g., by appropriate solvent concentration, choice of surfactant, use of chelating agents, use of swelling agents or combinations of these.
