Solar
The Solar market provides an especially large and interesting opportunity for SiGen. Today, there are two primary types of solar cells - - thin film and thick film. The thin film cells have excellent silicon utilization, but suffer from poor conversion efficiency. The thick films have typically high conversion efficiencies, but require excessive amounts of precious silicon. SiGen's layer transfer technology provides for thin films with good efficiencies. SiGen's layer transfer process is a "green" process since there is no sawing, grinding or other mechanical thinning of wafers. Today silicon is the major (approx 60%) cost component of solar cells. With SiGen's layer transfer process, the cost of producing solar cells with high efficiencies will be dramatically reduced, further stimulating an already exploding market.
The SiGen Solution: Reduction of Poly-silicon Consumption
It is important to note that SiGen's layer transfer process accomplishes the following:
- Thin film silicon content (<<2 grams per peak watt) with thick film efficiencies
- MINIMAL WASTED SILICON — no kerf losses
- "Clean process" — no silicon slurry to recycle or dispose
