Molybdenum metal (Mo, Molybdenum) with a high degree of optical reflectivity in nature, low resistance and high compressive stress and good ohmic contact with CuInSe2 is an indispensable electrode material for CIGS In this study, DC SPUTTER is used to deposite Mo metal on various substrates such as stainless steel, Al2O3, SiO2, etc, then combined use of SEM, AFM, XRD. In the measurement revealed that Mo deposition in the above-mentioned substrates with SiO2 as the best, but when produced in high-temperature Al2O3 shows less crackes than SiO2 substrates. In this study, the optimum parameters for depositing Mo metal thin films on SiO2 substrate is as following: substrate temperature 200℃, sputtering power 100W.
