Large-Scale Black Silicon Induced by Femtosecond Laser Assisted With Laser Cleaning

Abstract: Black silicon is a promising and effective candidate in the field of photoelectric devices due to the high absorptance and broad-spectrum absorption property. The deposition around the processing area induced by the pressure of SF6, gravity, and the block of the processing chamber interferes the adjacent laser ablation and hampers uniform large-scale black silicon fabrication. To solve the problem, femtosecond laser- induced black silicon assisted with laser plasma shockwave cleaning is creatively proposed in … Show more

“…Meantime, processes such as chemosynthesis [4], self-assembly [1], transfer printing [14], and laser direct writing (LDW) [5,6,[15][16][17] were used as alternatives with the possibility of yielding orderly or randomly distributed metal nanostructures with fascinating broader absorption bands. Among these processes, LDW can fabricate micro-nano metal structures in situ on the target surfaces in a high-resolution, large-scale, cost-effective, and rapid manner that fulfills the industrial prospects [16,[18][19][20][21]. Highly reflective metal surfaces can be tuned to black metals by laser inducing well-controlled metallic structures at a multiscale [5].…”

“…The synergetic effects of micro-nano hierarchical metal structures [6] provide suppressive external reflection, enhanced light trapping, and abundant nanoscale hotspots for absorption [22]. Despite these advantages, laser fabrication of BMAs involves protocols such as laser ablation and laser-induced dewetting [15,16], whereas laser-induced forward transfer (LIFT) of metal nanostructures for BMAs has not been reported yet.…”
