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.
