What Is Wet Dicing? A Comprehensive Report on Its Process, Advantages, and Industry Applications

    In the race to achieve mass production conversion efficiency exceeding 26% for high-efficiency silicon solar cells, a seemingly minor process step is emerging as the decisive factor—wet dicing. It directly governs the conversion efficiency, yield, and cost of batteries produced via frontier technical routes such as BC and TOPCon.
    Why is this process so critical? The key to achieving high-precision, strong-protection, and pollution-free processing lies not solely in the equipment itself, but begins with two non-negotiable foundational prerequisites: pre-production preparation and stable control of the chemical solution system. The robustness of these two fundamentals directly determines whether all subsequent process advantages can be fully realized.
    This article will provide a systematic explanation: What is wet dicing? Through a detailed process report, it will delve into its workflow, the indispensability of each step, and its specific applications within the silicon solar cell production process, revealing how it serves as an essential prerequisite for ensuring the efficiency and yield of mass-produced cells.
