Table 3

Effect of DC and RF sputtering techniques on molybdenum properties for CIGS [12, 86, 95, 97].

DC sputtering	Mo properties	RF sputtering
Larger grain size [97]	Grain size
	Optical reflectance	Higher optical reflectance [86]
Better crystallization [95]	Crystallization
Better surface morphology [97]	Surface morphology
	Resistivity	Lower resistivity [12]
