Abstract
The present invention relates to a process control system which can measure the physical properties of a CIGS thin film in real-time in a continuous production line of a CIGS thin film solar cell, more specifically to a system for real-time analysis of material distribution of a CIGS thin film comprising: a header, which comprises a laser irradiation unit producing plasma from the CIGS thin film by irradiating a laser beam to a part of the CIGS thin film; and a spectrum detection optical unit detecting a spectrum generated from the plasma; a transfer unit, which transfers the header at the same rate and to the direction with the transfer rate and direction of the CIGS thin film; and a spectrum analysis unit, which analyzes the spectrum detected by the spectrum detection optical unit.
