Energy Generation and the Terawatt (TW) Challenge

Humanity uses 12 TW of power today– 1 TW = 1,000 GW (Gigawatts)

World will need 15 TW by 2012Only 5 known sources of energy are available on a TW scale*

– Fossil fuels: Coal, oil, gas– Nuclear fuels– Solar

» Only inherently distributed solution» No fuel cost

Advantages of thin film PV

• Efficient and high performing materials– Direct bandgap semiconductors– Better energy output – kWh/KW – CIGS record at 19%+ conversion efficiency

• Significantly reduced costs– Less material usage

» Not affected by silicon supply shortages– Potential for improving costs throughout value chain

• Better aesthetics• Roadmap of glass-to-glass and flexible substrate

Solar Tomorrow: Building Integrated Photovoltaics

Power Buildings will become multi-$T market– BIPV is the fastest growing sector of PV– Building Integration leverages available surface area, installation costs, and proximity to

loads

Revolutionary products through efficient, durable thin-film solar cells embedded into traditional building materials

– Current products unsuitable and not cost effective

BIPV Applications• Roofing

– Most common BIPV application today

• Sunshades– Energy conservation and reduced building operating

costs

– Cooling load mitigation and glare control

– Easiest retrofit for PV

• Overhead glazing (canopies, skylights, atriums)• Curtain wall / Facades
