Abstract
We report a low temperature deposition process of kesterite Cu2ZnSnS4 thin film solar absorbers that combines magnetron sputtering of a Cu:Sn:Zn alloy target with evaporation of S chalcogen atoms with a linear valved cracked effusion cell. The sputtering of the metallic precursor is performed in DC and HIPIMS mode. The use of a pulsed sulfur evaporation cell avoids high energetic S anion bombardment of the growing film, allows excellent control of the atomic S flux through the film thickness and avoids target poisoning during film growth. The deposited film absorbers are nearly stoichiometric and show kesterite CZTS phase as indicated by X-ray diffraction, Raman scattering, optical absorption and photoluminescence measurements. This deposition method is suitable for its application in large-area inline manufacturing process, as it uses a magnetron sputtering source and a specially designed large area effusion cell.
