Description
Technical Field
The invention relates to the technical field of solar cell production, in particular to a solar cell production detection system.
Background
Since the solar cell is used outdoors and the nominal life is generally required to be 25 years, it is important to ensure the quality thereof, and among these tests, the detection of subfissure, developing crack, and the like is important. Generally, if a component with hidden cracks and obvious cracks is mixed in the component, the power or other electrical tests can show the defects, but the defects can not be determined in which component. Some subfractures do not necessarily immediately cause large shifts in electrical properties, however, develop over the course of years of use, leading to failure of the entire solar cell. It can be seen that the detection and analysis of defects of the solar cell are very important.
In the case of silicon, although it is an indirect bandgap semiconductor, in the vicinity of its bandgap, under a certain electric field bias at room temperature, its constructed p-n junction or p-i-n structure can still emit electroluminescence in the vicinity of the bandgap wavelength band, and its electroluminescence intensity is related to the diffusion length of the carriers. The corresponding fluorescence intensity is higher if the diffusion length is long. It is clear that if the relevant characteristics of silicon differ in different regions, different brightness characteristics are exhibited on the fluorescence image. If a crack occurs in a certain region, the influence of the crack should occur on the image acquired based on the fluorescence thereof. This is the principle by which information on defects in silicon solar modules can be obtained by means of electroluminescence image detection.
However, how does the detection of the room temperature electroluminescence image of the silicon solar cell be performed? When the solar cell is detected, problems in the production link must be considered. If the laminated and framed assembly is subjected to fluorescence detection, the battery can be directly electrified for fluorescence detection because the battery has certain strength. However, since the general manufacturer wishes to perform the inspection before lamination, the overall strength is weak, and the general manufacturer must face downward, and the self weight of the manufacturer must be considered, many problems are encountered.
