Conductive black silicon surfaces (CBSSs) are fabricated by Ag network‐assisted catalytic etching, with the Ag network buried in silicon for low reflectance. The CBSSs present a high light absorbance of 97% and good electrical conductivity of less than 10 Ω/□. The CBSSs might be used as anti‐reflection‐coating free light‐harvesting devices.
