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.

The conveyor includes a first plasmonic element and a second plasmonic element that individually supports a respective surface plasmon. The conveyor further includes a controller that provides controlled movement of a location of the respective surface plasmon on a surface of the plasmonic element. The controlled movement facilitates translocation of an analyte particle around a periphery of the respective plasmonic element using a high field region of the respective surface plasmon. The system includes the conveyor and an excitation signal source that provides an excitation signal having one or both of a polarization and a frequency that are controllably variable. The method includes exciting a surface plasmon with the excitation signal and moving a location of the excited surface plasmon.
