Centrotherm Photovoltaics AG (CTN.DE) announced the commissioning of a new polysilicon production facility for a customer in Taiwan.
The facility built for Taiwan PolySilicon Corp. (TPSI) offers an annual production capacity of 5,000 tons with an upgrade option to 8,000 tons. It is said to be the largest facility of its type in Taiwan, which is home to a burgeoning solar industry.
Centrotherm said the project marks a further expansion of its market presence in Asia.
For this project, TPSI is relied entirely on the development, technology and equipment know-how of Centrotherm SiTec, which bundles the Centrotherm Group’s silicon expertise. This Centrotherm subsidiary was responsible for the entire factory planning, and provided the basic engineering, process know-how, and reactors and converters that are required for polysilicon manufacturing. The vent gas recovery system developed by Centrotherm SiTec was also deployed.
Following the successful conclusion of the initial production phase, TPSI aims to grow further, and expand annual production capacity to up to 12,000 tons over the coming years. It should be noted by way of comparison that annual global solar polysilicon production volume is currently between 100,000 and 110,000 tonnes.
Centrotherm SiTec says the company commands a market share of around 40% for the key equipment items of reactors and converters for solar silicon manufacturing, and a still higher market share for complete factory design.
