METHOD AND APPARATUS FOR INSPECTING SOLAR CELL

摘要

Disclosed herein are a method and an apparatus for inspecting solar cells. According to an exemplary embodiment of the present invention, a method for inspecting solar cells includes: (a) preparing solar cells; (b) obtaining a photoluminescence image(s) by irradiating light to the prepared solar cells; and (c) determining a conversion efficiency rating of each solar cell according to brightness of the obtained image. Further, an apparatus for inspecting solar cells includes a stage unit that transfers solar cells; a light source unit that irradiates light to a surface of the solar cell transferred through the stage unit; a camera unit that obtains a photoluminescence image according to the light irradiated from the light source unit; and an efficiency determination unit that determines a conversion efficiency rating of each solar cell based on brightness of an image obtained from the camera unit according to preset programs.
