6 FAQs about [Solar Monocrystalline Silicon Inspection Department]

Can a monocrystalline silicon solar cell be tested by air-coupled ultrasonic testing?

So, for monocrystalline silicon solar cells, which have a thickness of 180 ± 20 μm, the entire thickness can be examined in a short time by Lamb waves. Besides, the fragile property of solar cells do not allow the contact test frequently. Thus, air-coupled ultrasonic testing method is proposed.

Why do solar cells need to be inspected during manufacturing?

During the manufacturing process and service of monocrystalline silicon solar cells, cracks are inevitably to void, which will affect the performance of photovoltaic conversion. Due to the requirements for safety and reliability, the materials should be examined during manufacturing and maintaining [ 1, 2 ].

How to detect silicon solar cells?

Nowadays, methods for the detection of silicon solar cells are mainly photoluminescence, electroluminescence and infrared thermal imaging techniques, etc. Although these methods can solve part of the problem, they're still constrained by some limitations, like the relatively high cost on equipment, low detection speed and so on [ , , ].

Why is quality control important for Si solar cells?

Thus, the quality control of the as-grown Si crystals is crucial to stabilize the manufacturing of modern Si solar cells. Semilab offers various solutions to control all the important material parameters in both multi- and monocrystalline silicon ingots.

Is there a nondestructive evaluation method for examination of cracks in solar cells?

Conclusion In this research, a nondestructive evaluation method for examination of cracks in monocrystalline silicon solar cells is established based on the non-contact air-coupled ultrasonic system.

Why are shiny silicon crystals visible on a cell?

Description: Shiny silicon crystals are visible on a cell locally. Some colour variation from cell to cell can be expected (ex. slightly different shades of blue), but largely varying colour across one cell can be a concern. Why it’s important: A shiny cell is reflecting significant light instead of absorbing it and generating power.
