Cadmium Telluride Thin-Film Module
A solar panel a few microns thick, using no silicon at all.
Crystalline Silicon Solar Module
The standard solar panel: silicon wafers, silver contact paste, glass and an aluminium frame.
Gallium Nitride Power Device
A switch that turns on and off far faster than silicon, so power supplies can shrink.
Leading-Edge Logic Chip
The most advanced processors, built on wafers that pass through hundreds of process steps.
