Original Abstract

The LBIC (light beam induced current) method is generally used for detection of local defects in solar cells. But this method is too slow. The LBIC analysis is widely used as a universal method for detecting local defects in the solar cell structure. Scanning of the solar cell surface with a single point light source (laser or LED focused beam) could take several hours of processing time depending on the required picture resolution. The fast way of defect detection is the electroluminescence imaging (EL). In EL imaging a forward bias is applied to the finished solar cells. A higher contrast between the white and the black area is attained in consequence of uneven distribution of current density. All process steps can be scanned by a CCD camera. In this work it is possible to compare LBIC method with electroluminescence - preferences and deficiencies, mutual comparison.
