| 摘要 |
The current invention describes a process and texturing solution for texturing a crystalline silicon substrate to provide a light trapping surface within a crystalline silicon based solar cell. In an embodiment the texturing process includes a pre-treatment of hydrofluoric acid followed by the application of a texturing solution that includes potassium hydroxide (KOH) and butanol. The application of the texturing solution may be followed by a hydrofluoric acid post-treatment. A combinatorial method of optimizing the textured surface of a crystalline silicon substrate is also described.
