Global solar manufacturing sector now at 50% utilization rate, says IEA
The International Energy Agency (IEA) says that global solar cell and module manufacturing capacity grew by around 550 GW in 2023. It reports that around 80% of the global PV manufacturing industry is currently concentrated in China, while India and the United States each hold a 5% share. Europe accounts for a mere 1%.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.
