What is the solar photovoltaics supply chain review?
The Solar Photovoltaics Supply Chain Review, produced by the DOE Solar Energy Technologies Office with support from the National Renewable Energy Laboratory, will help the federal government to build more secure and diverse U.S. energy supply chains.
What is the supply chain for solar PV?
The supply chain for solar PV has two branches in the United States: crystalline silicon (c-Si) PV, which made up 84% of the U.S. market in 2020, and cadmium telluride (CdTe) thin film PV, which made up the remaining 16%. The supply chain for c-Si PV starts with the refining of high-purity polysilicon.
How did China build a solar PV supply chain?
China also relied on a direct support approach to build its solar PV supply chain: government support included fiscal support 20, energy incentives 15, research and development (R&D) funding 5, tax rebates 20, land use incentives 15, and infrastructure investments 20.
What is the main energy security issue for the solar PV supply chain?
The main energy security issue for the solar PV supply chain is not the concentration of minerals, but of manufacturing capacity in China and in the hands of Chinese manufacturers.
Why is supply chain development important for solar photovoltaic (PV) capacity growth?
Supply chain development is crucial for solar photovoltaic (PV) capacity growth; however, most of its crucial value chain segments are concentrated in specific geographies such as China, Europe and the United States. Hence, from a sustainability perspective, it is critical that these supply chains become more diversified and resilient.
Is solar PV supply chain dependent on a single country?
Throughout the entire solar PV supply chain (i.e., polysilicon, ingots, wafers, cells, and modules), the shares of China and Chinese manufacturers often largely exceeded 80% and they were sometimes close to 100%. It is undesirable for any supply chain to be so dependent on a single country.
