Second, EL equipment, main performance and technical indicators Mainperformanceandtechnicaldataof EL equipment2.1, EL test take ct time is less than 1.2 s; The ct time of EL test is less than 1.2s.2.2 Test compatible cell size: 210mm210mm; Test compatible solar cell size: 210mmx210mm2.3 Camera type/pixel (CCD) : 5 million; Camera type/pixel (CCD): 5 million2.4 Resolution: ≤ 200μm Resolution: ≤ 200μm2.5 EL Detection Accuracy Rate: False detection rate < 2%, missed detection rate less than 0.2%; EL test accuracy: False rate < 2%, Missed rate < 0.2%2.6 Image uniformity test: > 95%; Image uniformity test: > 95%2.7 defect repeatability: > 99%@ general defect (if the gate is broken, count by quantity); 2.8. Handling of EL Defective Data: For the classification of EL defective data, a hot spot map should be created to facilitate the display of the frequency and concentration of occurrence. The gray value of EL should be able to display numerical values and avoid the appearance of light and dark patches at the component end. Definitions related to key technical indicators: a: Accuracy rate =1- [(False judgment + missed judgment)/Test Quantity] 100% False judgment refers to the situation where the defective interception battery cells, after manual determination, contain Class A battery cells that do not meet the defect standards. Missed detection refers to the situation where the battery cells that meet the Class A standards contain abnormal battery cells that exceed the Class A standards. b: Image uniformity It refers to the uneven imaging within a single cell of a solar cell caused by equipment, except for the influence of its own EL defects. Calculation formula: Image uniformity =1-(number of non-uniform images in the sample/number of samples)100%c: Defect repeatability test: It refers to the repeated testing of the same batch of battery cells twice, and the defects of the same battery cells remain consistent. Calculation formula: Repeatability =1-(number of defect differences/number of test samples)100%
