“…CuInGaSe2 and CuInS2Se2 [15]. A large number of techniques such as chemical bath deposition (CBD) [16][17][18][19], dip-coating [20,21], spray pyrolysis [22], proton exchange membrane [23], electro-active polymer [24], co-evaporation [25], thermal evaporation [26], solution growth technique [27], plasma polymerization [28,29], reactive diffusion [30], sol-gel [31][32][33][34], chemical vapor deposition [35], unbalanced magnetron sputtering [36][37][38][39], and successive ionic layer adsorption and reaction [40] are extensively used for the deposition of film based products.…”
