Photoelectrochemical texturization of n-type multicrystalline silicon

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).
