[0002] In the rapidly developing solar photovoltaic industry, as the core component of a photovoltaic module, the performance stability and reliability of a solar cell chip are directly related to the power generation efficiency and safe operation of the entire photovoltaic system. However, during the actual use of a solar cell chip, it will inevitably encounter various harsh environmental conditions, among which a humid environment is a particularly important consideration. Rain, dew, fog, and a high-humidity environment may all have an adverse impact on a solar cell chip, such as causing corrosion, a decrease in insulation performance, or even leakage problems. These problems will not only reduce the power generation efficiency of the photovoltaic module but may also pose safety hazards, such as fires or electric shocks.

[0003] To ensure the stability and safety of a solar cell chip in a humid environment, wet leakage testing has become an essential part of the photovoltaic module production process. Traditional wet leakage testing methods often use a fixed water tank, and the solar cell chip is manually placed into the water tank for testing. This method has many drawbacks, such as cumbersome operation, low efficiency, and difficulty in adapting to solar cell chips of different sizes. In addition, since the solar cell chip needs to be frequently taken out and put into the water tank during the testing process, it may also cause unnecessary physical damage to the chip.
