Abstract. Creation of laser-induced morphology features of the c-Si and mc-Si with the use of 532 nm Nd: YAG laser nanosecond pulses in vacuum and СО2 atmosphere is investigated. Specimens of 20×20 mm laser-textured mc-Si wafers with typical pillar array structures of aspect ratio (depth to width) greater than or equal to 3 and weighted effective reflectance below 3 % are obtained.
Keywords: multicrystalline silicon, laser texturing, solar cells.
