Each of the protrusions (12′) has a tip (22) with a radius of curvature, r, ranging from about 0.1 nm to about 100 nm. The second electrode (18) is positioned relative to the first electrode (16) such that the electrodes (16, 18) together produce an electric field (EF) when a voltage bias is applied therebetween. The electric field (EF) has a field distribution that creates a stronger field gradient at a region proximate to the tips (22) than at other portions of the substrate (12).

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.
