In PV manufacturing, quality problems that originate in the silicon ingot stage propagate through every subsequent process. A crack in a seed crystal can cause an entire ingot to break during pulling. An undetected flaw in a square ingot leads to batch-level wafer breakage.
The Cost of Upstream Defects
Seed crystal cracks lead to ingot breakage during pulling, resulting in complete material loss. Ingot cutting errors waste high-purity silicon from re-cuts. Square ingot cracks elevate wafer breakage rates and reduce yield. Wafer defects reduce cell efficiency and cause product downgrading.
Our Solution
Vision Potential offers a complete upstream testing suite including the SC-Seed for 6-in-1 seed crystal inspection, SC-Ingot-LR for auto-marking optimal cutting positions, SC-MC-BI for square ingot microcrack detection, SC-DIM-BI for precision dimension measurement, and SC-SPL for silicon wafer PL inspection.
Investing in upstream testing is far more cost-effective than dealing with downstream quality failures.
