电致发光缺陷检测仪的成像性能评估
Evaluation of imaging performance for electroluminescence defect detector
摘要
Abstract
Technical indexes such as resolution,image uniformity,and image display were analyzed and compared,aiming at the inconsistency of current imaging performance of electroluminescent(EL)defect detector in combination with electroluminescent principles of Photovoltaic(PV)modules.A rapid and effective on-line detection technique for PV modules was proposed.Corresponding detection and assessment devices were developed,and related test experiments were implemented.The experiment results show that for a visual judgment of images on test board of resolution ratio pasted in modules,the technique can realize a detection with the highest resolution of 1.98 lp/mm and a simulative detection of minimum single stripe flaw with line width of 0.1 mm,thus guaranteeing more accurate and effective defect detection for PV modules and promoting production quality of PV industry.The assessment technique is feasible to EL defect detector in production line of PV modules and can satisfy current detection demands of photovoltaic industry.关键词
