Wafers become Semiconductors…which become the electronics we use every day.
Wafers also become solar cells…which generate the clean power of today and tomorrow.
We make the wafers.

6. Solar Cells and Wafers
• Thin wafers of silicon
• Similar to computer chips, bigger and cheaper
• Light carries energy into cell
• Cells convert sunlight energy into electric current-
they do not store energy
• Sunlight is the “fuel”
