The core objective of this CPV project is to increase the conversion efficiency of solar energy and save manufacturing cost by focusing sunlight onto small cells with higher efficiency through optical devices. By 2010, the following specifications were achieved:

• Module efficiency up to 25.4% (by fi eld-test measurement)
• High concentration up to 1,000 times
• High angle tolerance: ±1º
• Super-thin structure: ≤100 mm (only ½ of conventional CPV products)

• Prototypes of CPV modules
• Full set of CPV solution including optical structure, packaging and thermal design

This project intends to establish lithium (Li) ion battery with ALEA in the anode. The new ALEA anode composition and formulation will be optimized by using three research approaches: nanostructure development, composite design and porous conductive matrix analysis. ALEA is compatible with typical battery fabrication process, hence capable of up-lifting the Mainland’s industrial competitiveness.

Design and synthesis of Li ion battery anode with the following features:

• Patented nano-structure architecture
• Reversible capacity ≥450m Ah/g
• Cycle life ≥400 cycles
• Sluggish charge rate: 0.5C
• Cost per capacity <1X
