China-based photo voltaic poly-Si wafer maker GCL-Poly Energy, in response to shrinking demand, has targeted advertising and marketing on black poly-Si, quasi-mono-Si fashions and mono-Si wafers, in accordance with trade sources.
PERC photo voltaic cell makers choose mono-Si wafers to poly-Si ones, as cells made out of the previous supply higher cost-efficiency efficiency, leading to shortages of the previous and shrinking demand for the latter, the sources stated.
Quasi-mono-Si wafers are produced utilizing present poly-Si wafer tools. Compared with mono-Si wafers, quasi-mono-Si wafers have barely decrease vitality conversion charges however are cheaper to supply, the sources famous.
GCL-Poly hopes black poly-Si wafers can keep the enterprise of the general poly-Si section, and quasi-mono-Si wafers can compete with mono-Si ones, the sources stated.
GCL-Poly has stepped into manufacturing of mono-Si wafers by means of cooperation with the second largest China-based mono-Si wafer maker Zhonghuan Semiconductor.
GCL-Poly is increasing annual manufacturing capability for black poly-Si and quasi-mono-Si wafers collectively to 12GWp by year-end 2019 and 15GWp in 2020; and that for mono-Si wafers to 8GWp in 2020, the sources indicated.
China-based vertically-integrated PV maker CSI has stepped in manufacturing of black poly-Si and quasi-mono-Si wafers. CSI has used in-house-produced 166mm x 166mm poly-Si wafers, that are bigger than regular sizes, to make photo voltaic cells, with a PV module manufactured from 60 of those outsized cells having energy output of 360W, the sources famous.
