Scenarios Concerned Essentially For Further Technologies of Most Cost Effective C-SI Products
The manufacturing cost of c-Si PV products decreased about 90% in the past ten years that realize the grid parity of solar energy in some areas. In order to push the PV grid parity widely in the world further cost down of levelized cost of energy (LCOE) is required. In the presentation the scenarios concerned essentially for further technologies of more cost effective PV products is discussed. It is considered that 30% to 50% cost down of PV products with the innovative technologies including FBR poly-silicon, ultrathin wafer, high efficiency solar cell and new module structure, is possible in the next several years. Metallization wrap through (MWT) technology is introduced and considered to be very promising since it could be well compatible to these technologies for further PV products cost down.
