Applied Vericell Solar Wafer Inspection System

The Applied Vericell Solar Wafer Inspection system is the industry’s most advanced fully automated bare wafer inspection tool for crystalline silicon PV wafer and cell production. The Vericell system’s multiple integrated inspection modules automatically evaluate each wafer to find and eliminate defective wafers from production, resulting in significant manufacturing savings. It measures and reports on a wide range of parameters including wafer thickness, thickness variations, warpage and resistivity. The Vericell system also detects defects including saw marks, chipped edges, damaged chamfers, stains, pin holes and micro-cracks.

Through the use of state-of-the-art photoluminescence (PL) technology, the Vericell system can detect oxygen circle to increase cell line yield. By removing oxygen circle wafers, Vericell customers can achieve overall improvement in their factory’s average cell efficiency yield and increase factory profitability. In addition, the Vericell system delivers the lowest breakage rate in the industry with the highest inspection throughput of up to 16,000 wafers per hour.

Vericell provides three types of equipment for full, half and rectangular wafer sizes used in the solar wafer and cell industry.
