Aurora Visualize combines high-resolution doped layer measurements from Aurora’s DM series products with wafer positions within the furnaces to visualize and characterize process performance. This enables PV cell manufacturers to easily manage and control the performance of emitter formation with a complete understanding of process dynamics, batch after batch.
By presenting easy to interpret 3D graphical visualizations, Visualize enables production operators to quickly detect, diagnose and resolve process issues. Process engineers can much more easily and efficiently adjust and optimize furnace parameters leading to higher yield of top quality cells. This opens the door to substantial cost savings for solar cell manufacturers and has a positive impact on profitability.
Visualize supports the manufacturing team by continuously monitoring the quality of every emitter and comparing them to SPC targets. Out-of-specification conditions are alarmed and highlighted in intuitive graphical displays that make it easy for operators and process engineers to diagnose issues and quickly address areas of concern. The benefits of such tight monitoring and control are reduced downgraded cells, higher average cell electrical efficiency, increased production line throughput, and elimination of manually intensive sampling and testing of wafers by lab technicians.
