Patents by Inventor Sagar Vijay

Sagar Vijay has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Silicon texturing formulations
    Patent number: 9099582
    Abstract: The present disclosure includes a texture formulation that includes an aliphatic diol, an alkaline compound and water which provides a consistent textured region across a silicon surface suitable for solar cell applications. The current invention describes silicon texturing formulations that include at least one high boiling point additive. The high boiling point additive may be a derivative compound of propylene glycol or a derivative compound of ethylene glycol. Processes for texturing a crystalline silicon substrate using these formulations are also described. Additionally, a combinatorial method of optimizing the textured surface of a crystalline silicon substrate is described.
    Type: Grant
