Isofoton and Hankook Silicon are planning to build what's being called one of the world's largest polysilicon factories in the Spanish region of Andalusia. The South Korean materials house will reportedly invest €600m and supply technology for the 10,000MT Silicio Energía plant, to be located in Los Barrios, Cádiz.

The facility, which originally was set to have 2,500MT capacity, was begun a few years ago but delayed by the global economic crisis. Isofoton was bought by Affirma and Top-Tec, a move which led to majority shareholder Angel Luis Serrano taking over as president of Silicio Energía last year. The chief exec is said to have pushed for reviving and expanding the polysilicon project.

The Regional Government of Andalusia's Idea agency is working closely with Silicio Energía to attract similar investment as part of the regional government's photovoltaic industry push. The establishment of the factory should create more than 1000 jobs.

The timeline for construction and completion of the factory was not disclosed.
