The narrow process window of the standard alkaline texturing process with KOH and IPA often leads to poor texture and is very difficult to control.
GP ALKA-TEX .+2, is a solution to improve texture quality and to broaden the process window.

• Higher uniformity of pyramid structure
• Increased process stability and reproducibility
• Increased bath lifetime and throughput
• Lower consumption of standard chemicals
• Pyramid size directly tuneable
• Reduced process time
• More wafer qualities with one recipe
• Higher cell efficiency (up to 0.3% increase)
• Environmentally uncritical
