Abstract
Provided is an apparatus that can check in real time a process of removing light induced degradation using precise carrier injection through an AC power supply device (power unit). An apparatus for reduction of light induced degradation with carrier injection includes: a housing in which high-temperature heat treatment is performed on a solar battery cell; a heating unit that is formed in the housing, on which the solar battery cell is seated, and that heats the solar battery cell; a jig unit that is formed in the housing and fixes the solar battery cell to the heating unit by pressing the solar battery cell seated on the heating unit; an LED array unit that has a plurality of LED light sources and radiates light to the solar battery cell; and a driving unit that is coupled to the jig unit and the LED array unit and rotates the jig unit or the LED array unit.
