Jin reported that in 2023, China accounted for 96% of global ingot and wafer production. She added that the wholesale switch within PV manufacturing from multicrystalline to monocrystalline technology, in and around 2018, was decisive for China''s dominance of the production step. That dominance has extended upstream.
