AB Chemical texturization of mc-Si wafer surfaces produces different patterns, allowing for a diffuse surface which increases the light absorption and the final cell efficiency. Alkaline chemical texturizations are typical for c-Si. Chemical texturizations based on the HF:HNO3solution are a general option for mc-Si, giving different surface morphology textures: pits, motheyes, grooves, etc. Laser texturization processes have been also explored. Texturization processes can introduce detrimental defects in the material, e.g. laser texturization canproduce residual stresses or even amorphous phases.
