6 FAQs about [Andorra polysilicon solar panel]
Is polysilicon a viable raw material for EU-installed solar power?
Polysilicon is a raw material required for 3 growth markets EU-installed solar capacity needs to quadruple from 200 to 750 GWp by 2030. To meet this target, EU polysilicon factories are required. At least a production capacity amounting to 150.000 MT/year.
What is polysilicon used for?
Here is a primer. Polysilicon, a high-purity form of silicon, is a key raw material in the solar photovoltaic (PV) supply chain. To produce solar modules, polysilicon is melted at high temperatures to form ingots, which are then sliced into wafers and processed into solar cells and solar modules. Source: National Renewable Energy Laboratory, 2021
Where is polysilicon made?
Currently, however, over 90% of the polysilicon manufacturing capacity is in China. Now is the opportunity to create strategic independence and create low carbon footprint solar panels by producing high quality polysilicon based on renewable energy in Europe.
Why do we need EU polysilicon factories?
To meet this target, EU polysilicon factories are required. At least a production capacity amounting to 150.000 MT/year. Two major drivers determine competitiveness in the solar industry, lower panel costs and higher efficiencies. High purity, constant quality and security of supply are paramount for our customers.
Why has the polysilicon industry consolidated?
The polysilicon industry has increasingly consolidated, with the top-five companies accounting for 73% of global production in 2020 compared to 60% in 2017, according to BNEF. This is mainly due to a number of companies shutting down capacities in recent years after a period of overcapacity.
What technology is used to make polysilicon?
Three are three main technologies to produce polysilicon. The ‘modified Siemens process’ is currently the dominant technology in China. Trichlorosilane (TCS) is produced using two readily available metallurgical-grade silicon (of 95-99% purity) and liquid chlorine.
