There are mainly two types of slicing processes, wire saw slicing and diamond wire slicing that result in different efficiencies of solar cells. The wire saw slicing method has a lower cost, but the diamond wire slicing has a higher productivity and the wire material has relatively higher durability. Therefore, the diamond wire slicing process becomes the mainstream and its development cannot be ignored. However, the lattice structure of silicon has different degrees of damage when the diamond wire slicing was applied. The surface roughness of diamond wire cutting was inadequate after etching process because the produced silicon wafers have higher reflectivity and lower efficiency. Therefore, this study uses hydrofluoric acid, nitric acid and sulfuric acid with different proportions for the purpose of finding the best etchant recipe to increase the surface roughness of the diamond wire cutting wafers for more stringent customers’ demand.
