China's silicon dominance

Trade sanctions appear to have done little to dent China's dominance over the solar crystalline silicon production chain, with the country still dominating each production step.

With trade wars continuing across the globe, it is worth examining the PV supply picture at two different points: the quarter in which the first of the trade investigations began and the end of the current year. The figure below shows these points in Q4’11 and Q4’14, highlighting snapshots of the crystalline silicon (c-Si) PV production chain. The figure focuses on c-Si PV as it regularly accounts for more than 90% of solar PV production and almost all trade investigations thus far have excluded thin-film PV components.
