SunEdison said that its high pressure fluidized bed reactor (HP-FBR) technology being ramped at its new joint venture facility in Korea will provide source polysilicon to enable 400 watt peak PV panel performance at a cost of US$0.40 per watt peak by 2016.

The HP-FBR technology developed by SunEdison is claimed to produce high purity polysilicon 10 times more efficiently than standard Siemens processes, while requiring 90% less energy consumption. 

"Solar energy is at a transformational moment in time and innovative technology is what will power that transformation," said Ahmad Chatila, CEO of SunEdison. "Our latest advance is a leap forward in solar technology and will enable solar power to become the lowest cost energy solution – not just an alternative to other renewables, but the cost-winner over fossil fuels as well."    

The company also noted that with the ramp of the new polysilicon plant in Ulsan, Korea with partner Samsung Fine Chemicals and operated with SunEdison Semiconductor the facility had been expanded to produce 13,500MT per annum, compared to the initial designed capacity of 10,000MT. 

Full capacity of the plant is expected to be reached in the first quarter of 2015.  

Rival PV manufacturer’s such as Yingli Green Energy have module costs below US$0.50/W, with the conventional Siemens process used by GCL New Energy, the largest (65,000MT) producer of polysilicon and based in China.
