“…Various methods have been used to prepare CuInS 2 photoabsorber layers, such as plasma sputtering deposition [12,13], spray pyrolysis [14,15], thermal evaporation [16], chemical bath deposition [1,17], and electrodeposition [18,19]. For industrial applications, electrodeposition is a non-vacuum method for the preparation of ternary semiconductors such as CuInS 2 [20] or CuInSe 2 [21].…”
