Abstract

See full text

Disclosed is a method of forming a chalcogen compound thin film suitable for use in a light-absorption layer of a solar cell. The method includes manufacturing a precursor liquid including an Sn precursor material and an S precursor material, applying the precursor liquid to form a precursor film, and heat-treating the precursor film. The Sn precursor material and the S precursor material are liquid materials. The present invention provides a method of forming a chalcogen compound thin film using a liquid precursor material without a sulfurization process, thereby forming a high-quality SnS thin film at low cost using a process which is suitable for mass production. Further, the light-absorption layer is formed using a process which is suitable for mass production, thus enabling the manufacture of a solar cell including the chalcogen compound thin film at low cost.
