GCL-Poly breaks ground on new polysilicon center

• Polysilicon producer GCL-Poly has started construction on the first phase of a brand-new 54,000 MT polysilicon manufacturing center.

The project was officially introduced earlier today (8 September 2020) as well as has a complete planned capability of 100,000 MT. Launched with a total financial investment of RMB4.7 billion (US$ 686.6 million), the center is to be constructed in 2 phases. Stage 1 will establish a center with a preliminary capability of 30,000 MT by June 2021, to be increased to 54,000 MT by the end of next year.

GCL-Poly is to utilize its fluidised bed reactor (FBR) approach for silicon mass production at the facility, made use of for constant crystal pulling of monocrystalline silicon and priming of high-efficiency polycrystalline silicon ingots.

The company's FBR technique professes to have a shorter production procedure with fewer post-processing steps while additionally flaunting a 30% cheaper financial investment expense. Power intake is also nearly two-thirds (65%) less than more conventional methods and needs 30% much less work.

FBR innovation has actually long since been held as a prospective service to delivering lowest-cost polysilicon at high pureness degrees, with GCL-Poly acquiring properties including FBR processes from obsolete solar firm SunEdison in 2016. In its newest monetary update issued earlier this month, GCL-Poly claimed it was to switch over manufacturing at its Xuzhou base to granular silicon rods making use of FBR technology over the coming years, a shift which would lower that center's nameplate capacity by virtually half.

According to experts, with the fast expansion of monocrystalline silicon production ability and also the rise in the proportion of monocrystalline silicon re-injection materials, paired with the advantage of no crushing requirement to avoid the introduction of pollutants, the FBR silicon bit has the possible to change rod-shaped silicon as an innovative alternative for the future generation of silicon product innovation.

The development revealed today, based on Jiangsu Zhongneng's existing yearly silicon fragment production ability of 9,000 MT, will reduce the increasing need for re-injected products in the monocrystalline silicon market and supply GCL wise production items with even more modern, much better procedure as well as lower-cost for China's PV market grid parity.
