In recent years, chalcopyrite semiconductor thin films are being intensively investigated for low-cost terrestrial phovoltaic applications. One prerequisite for solid state solar cells is the strong interface to allow the intimate contact between semiconductors. The paper studied the possibilities of CuInS2 thin film surface control by using sodium dodecyl sulfate as additive in precursors’ solution in concentration below and above the critical micelle concentration of the surfactant in solution. The sample with the amount of surfactant lower than the critical micelle concentration in precursors’ solution has the highest surface energy value. The use of surfactant conducted to increased preference for formation of thin films with peaks, the higher peaks being obtained for the thin films obtained from solutions with surfactant concentration higher than critical micelle concentration.
