  • Patent number: 9876128
    Abstract: A method for preparing a monocrystalline silicon substrate surface for a subsequent texturing step, the method comprising: removing contaminants from the surface by contacting the surface with a cleaning solution; etching the pre-cleaned surface with an aqueous solution comprising from 12 to 19% by weight, of KOH and/or NaOH; rinsing the etched surface with an aqueous medium at pH from 7 to 10; and contacting the rinsed etched surface with ozonated deionized water at pH from 2 to 4.5, thereby converting the rinsed etched surface into a prepared surface. A method for texturing the prepared surface is also provided.
    Type: Grant
