Polycrystalline silicon is a material consisting of
multiple small silicon crystals. The manufacture
method is to solidify the melting silicon (to get
the polycrystalline silicon ingots, the melting
silicon will be casted via slowly cooling from
bottom to top in the squared crucible, then the
ingots to be cut in bricks, then be sliced into
wafers). |

| Multi-crystalline silicon wafers play a leading role in the solar PV wafer market, owing to lower cost and higher volume manufacturing, multi-wafers win the superior position to mono- wafers. However, in response to the market demand and driving, how to achieve highest conversion efficiency per square inch is the biggest challenge of the solar technology development. To avoid the higher cost disadvantage of mono-wafers, the development of mono-like wafer technology becomes one of the most important research topics. Mono-like wafers can be produced with the original tools and processes, and provide superior conversion efficiency potentially. The company has developed preliminary mono-like wafer technology, and continue the work in product quality and production technology improvement according to customers’ requirements , which will enhance the product competitiveness and competitive advantage for the company. |
