Description

Technical Field

[0002] With the rapid development of the photovoltaic field, the market competition of silicon wafer batteries is becoming increasingly fierce, and the quality requirements for battery chips are getting higher and higher. The conversion efficiency of battery chips is the most important parameter of crystalline silicon solar cells. Avoiding the situation of overestimated or underestimated conversion efficiency of battery chips is an important task in the production process. Therefore, ensuring the stability of IV testing has great value and significance for reducing costs and improving efficiency of battery chips. When the battery chip passes through the testing system, it will trigger a flash. The battery chip and the light intensity / spectrum are irradiated, and the upper and lower IV probes are energized synchronously. The electronic load will scan the battery from the short-circuit state to the open-circuit state to obtain the corresponding data of electrical performance.

[0003] If some battery chips have different thicknesses or serious internal defects, in the actual detection process, the battery chips with problems will cause fragments when sucked by the automated equipment or bitten by the probes. The fragments will fall below the IV test needle row, and the reflection of the fragments will affect the IV electrical performance test. In addition, the cleaning and maintenance of the fragments are relatively complex and the cycle is long, which causes great trouble to the production. Content of the Utility Model
