The investment from Wacker, one of the world’s largest polysilicon makers, adds another layer of credibility to Massachusetts-based 1366’s plan to disrupt the global solar supply chain with its “Direct Wafer” technology – and comes on top of the company’s recent deal to sell its wafers to Hanwha Q Cells.

Wacker – which recently finished building a $2.5bn polysilicon factory in the US state of Tennessee – will supply 1366 with the “majority” of the polysilicon it will use at its 250MW wafer factory that is under construction in New York and due online next year.
