Pyrolytic carbon coated black silicon. [PDF]

Sci Rep, 2016
AbstractCarbon is the most well-known black material in the history of man. Throughout the centuries, carbon has been used as a black material for paintings, camouflage and optics. Although, the techniques to make other black surfaces have evolved and become more sophisticated with time, carbon still remains one of the best black materials.

Bactericidal activity of black silicon. [PDF]

Nat Commun, 2013
Black silicon is a synthetic nanomaterial that contains high aspect ratio nanoprotrusions on its surface, produced through a simple reactive-ion etching technique for use in photovoltaic applications. Surfaces with high aspect-ratio nanofeatures are also common in the natural world, for example, the wings of the dragonfly Diplacodes bipunctata. Here we

Porous Au/Ti Bilayer Thin-Film Getters Based on Black Silicon for MEMS Vacuum Packaging [PDF]

Micromachines
Porous thin-film getters are extensively utilized in the field of MEMS vacuum packaging. Nevertheless, their effectiveness is frequently constrained by the comparatively modest effective surface area of conventional planar structures.

Black silicon as a platform for bacterial detection. [PDF]

Biomicrofluidics, 2015
Surface-enhanced Raman scattering (SERS) shows promise for identifying single bacteria, but the short range nature of the effect makes it most sensitive to the cell membrane, which provides limited information for species-level identification. Here, we show that a substrate based on black silicon can be used to impale bacteria on nanoscale SERS-active ...

Enhanced near-infrared absorber: two-step fabricated structured black silicon and its device application [PDF]

Nanoscale Research Letters, 2018
Silicon is widely used in semiconductor industry but has poor performance in near-infrared photoelectronic devices because of its high reflectance and band gap limit.

On the Formation of Black Silicon Features by Plasma-Less Etching of Silicon in Molecular Fluorine Gas [PDF]

Nanomaterials, 2020
In this paper, we study the plasma-less etching of crystalline silicon (c-Si) by F2/N2 gas mixture at moderately elevated temperatures. The etching is performed in an inline etching tool, which is specifically developed to lower costs for products ...

N-type Black Silicon Solar Cells

Energy Procedia, 2013
AbstractBlack silicon is an interesting surface texture for solar cells because of its extremely low reflectance on a wide wavelength range and acceptance angle. In this paper we present how black silicon (b-Si) texturization can be applied on the boron doped front surface of an n-type solar cell resulting in an efficiency of 18.7%.

An Investigation on a Crystalline-Silicon Solar Cell with Black Silicon Layer at the Rear. [PDF]

Nanoscale Res Lett, 2017
Crystalline-Si (c-Si) solar cell with black Si (b-Si) layer at the rear was studied in order to develop c-Si solar cell with sub-band gap photovoltaic response. The b-Si was made by chemical etching. The c-Si solar cell with b-Si at the rear was found to perform far better than that of similar structure but with no b-Si at the rear, with the efficiency
