This document discusses process visibility and optimization in the solar PV value chain. It introduces Prediktor, a company that provides consulting services and industrial IT solutions to optimize manufacturing processes. Prediktor helps solar PV manufacturers reduce costs, improve quality, and increase throughput by integrating machine data, providing analytical tools, and consulting on process optimization. The document outlines challenges manufacturers face without effective data collection and analysis systems, and how Prediktor's solutions can help provide real-time visibility into production data to identify and address issues.

1. AgendaProcess visibility and PV value chain optimization27. May 2010Henrik HasselManaging Director, Prediktor China

2. 多晶硅材料silicon硅片wafer硅锭ingot电池cell组件modulePV 电厂Power plantSolar PV production chainReduce costs

3. Improve quality

4. Increase throughputGoal: more solar energy at continuously lower costs!

5. 硅片waferSample case, wafer productionHigh proportion of wafers with unacceptableresistivity levels.... What do these wafers have in common?

6. What is the root-cause behind this?

7. How can we find out as fast as possible?

8. What corrective actions do we need to take?

9. All wafers come from bricks produced in line #3, furnace #2

10. This furnace has high deviation in energy consumption

11. Production is stopped, maintenance checks furnace #2

12. Gas leakage identified and fixed
