Polysilicon prices rose for a sixth straight week as plant outages extend a shortage of the material that’s key to making solar panels.
The average cost of the most expensive grade of polysilicon rose 1.9% to 291.6 yuan ($43.50) a kilogram on Wednesday, according to a statement from the China Silicon Industry Association. Prices are at the highest level since late 2011.
