    摘要: A substrate for photovoltaic device includes a textured surface formed from silicon-based material. The textured surface includes a plurality of cones uniformly distributed across the textured surface. The uniformly distributed cones are configured by etching from a top surface of the substrate using a self-assembled solder dot mask evaporated on the substrate prior to etching. The cones are uniformly distributed as a result of gettering a process chamber prior to forming the solder dot mask. The cones have a height/width ratio between about 1 to about 4, and the cones have a density between 108 to 109 cones/cm2.
