Taking advantage of the electrochemical formation of macropores in aqueous HF under illumination, we have developed an efficient photoelectrochemical (PEC) texturization on n‐type multicrystalline Si (mc‐Si) wafers which leads to a decrease in the reflectivity of solar cells. An optimized mc‐Si texturized surface exhibits an 8.5% effective reflectivity ( λ = 400–1000 nm, AM1.5 standard solar illumination). (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
