Comparative study of different approaches of multicrystalline silicon texturing for solar cell …

Multicrystalline silicon surface texturing is a key issue to fabricate low-cost and high-efficiency solar cell in mass production level. For monocrystalline silicon, the well-established texturing method is anisotropic etching with aqueous solutions of potassium or sodium hydroxide, which results in the surface covered with pyramids.
