Silicon Solar Cells: Materials, Devices, and Manufacturing
About 200 wafers are etched in a batch process. Monocrystalline silicon substrates are subsequently textured using a low-concentration etch containing 2% sodium hydroxide and isopropyl alcohol (IPA). The (100) crystal planes are etched relatively faster than other planes. This results in the intersection of (111) planes and the exposed surface forms with tiny
