In the production and research and development process of photovoltaic cell, IV test probe row draws the current-voltage (IV) characteristic curve of battery by applying different voltage and measuring corresponding current change. This curve can intuitively reflect the key parameters such as photoelectric conversion efficiency, fill factor, open-circuit voltage and short-circuit current of battery, and it has important significance for optimizing battery design and production process. With the continuous development of photovoltaic technology, the structure of battery is increasingly complex, and the requirements of IV test probe row are also correspondingly improved, not only high precision and stability are needed, but also good compatibility and flexibility are needed to adapt to different types and specifications of battery test requirements.

[0003] In the prior art, the test of 0BB battery has significant drawbacks. As an innovative battery piece structure design, 0BB battery cancels the main grid line on the front of the traditional battery piece, and instead adopts a more refined interconnection method to collect and transmit current, aiming to reduce shading loss, increase effective illumination area and reduce silver paste consumption. However, this design feature makes 0BB battery face challenges in IV test. Since 0BB battery has no main grid line as the path of current collection, the probe row of the prior art often cannot accurately press on the grid line during the test process, resulting in inaccurate current collection. This inaccuracy will directly affect the accuracy of IV test results, and thus cannot truly reflect the actual performance of 0BB battery. In addition to the above reasons, there is a possibility that in the prior art, most of the probe rows do not have a protection mechanism under them, which causes the bottom end of the probe to be easily worn and damaged during daily storage, use or handling, which also causes inaccurate current collection. Therefore, in view of the characteristics of 0BB battery, new IV test probe row technology needs to be developed to ensure the accuracy and reliability of the test. SUMMARY
