Fabrication system of cigs thin film solar cell equipped with real-time analysis facilities for profiling the elemental components of cigs thin film using laser-induced breakdown spectroscopy

A copper indium gallium selenide (CIGS) thin film solar cell fabrication process system comprising:

• an object transfer section to continuously transfer a process object for fabrication of CIGS thin film solar cells;
• a thin film fabrication process section to perform a CIGS thin film fabrication process on the process object during transfer;
• at least one header including at least one laser irradiation sectional to radiate a laser beam to CIGS thin film manufactured by the thin film fabrication process section, at least one spectroscopy detection optical section to detect the spectroscopy from a plasma generated CIGS thin film by the irradiated laser beam, and a beam irradiation positioning section to adjust an irradiation position of the laser beam;
• wherein the header is located above the CIGS thin film;
• a header transfer section combined with a transfer path of the object and moving the header in the same speed and direction as a moving speed and a moving direction of the CIGS thin film manufactured by the thin film fabrication process section;
• a spectroscopy information storage section in which a spectroscopy state information is stored;
• a spectroscopy analyzing section connected electrically to the spectroscopy detection optical section to analyze a material distribution state within the CIGS thin film from the spectroscopy detected by the spectroscopy detection optical section based on the information stored in the spectroscopy information storage section;
• a process control section connected to the spectroscopy analyzing section to control the thin film fabrication process section based on the material distribution state within the CIGS thin film analyzed by the spectroscopy analyzing section;
• and
• a scribing section to pattern the CIGS thin film manufactured by the thin film fabrication process section.
