Texturing the surface of crystalline silicon wafers is a very important step in the production of high-efficiency solar cells. Alkaline texturing creates pyramids on the silicon surface, lowering surface reflectivity and improving light trapping in solar cells.
Silicon surface texturing is an effective way of light trapping for solar cells application [9, 12]. Light trapping is typically achieved by altering the way the light travels by making it incident on an angled surface in the solar cell.
The laser texturing processes were carried out in SF 6, Cl 2, helium (He) or nitrogen (N 2) ambient using femto-second (fs) or nano-second (ns) lasers. The balance between the transverse mode order and laser power is reported to be the key for generating smaller and uniform textures suitable for solar cell applications .
Uniform texture generation across the wafer surface is crucial for large area wafer based solar cells, as texture uniformity has significant impact on the uniformity of phosphorous diffusion, the effectiveness of surface passivation and silver (Ag) contact formation to diffused emitter , , , , .
