FAQs about The materials for photovoltaic panels are always in short supply

Which raw materials are in short supply in PV power systems?

Beylot et al. (2019) quantified the demand for raw materials such as Al and Cu in PV power systems and calculated the risk of raw material consumption. Gervais et al. (2021) found that gallium, indium, and selenium are in short supply in the PV market, and that silicon is also at some risk of supply.

Is polysilicon a bottleneck for solar PV?

Global capacity for manufacturing wafers and cells, which are key solar PV elements, and for assembling them into solar panels (also known as modules), exceeded demand by at least 100% at the end of 2021. By contrast, production of polysilicon, the key material for solar PV, is currently a bottleneck in an otherwise oversupplied supply chain.

Are solar PV supply chains cost-competitive?

Currently, the cost competitiveness of existing solar PV manufacturing is a key challenge to diversifying supply chains. China is the most cost-competitive location to manufacture all components of the solar PV supply chain. Costs in China are 10% lower than in India, 20% lower than in the United States, and 35% lower than in Europe.

What are the different types of photovoltaics?

For comparison, we chose six different PV types, using different materials or materials classes: c-Si (refs. 37, 38), GaAs (ref. 39), Cu (In,Ga)Se 2 (ref. 40), Cd (Te,Se) (ref. 41), metal halide perovskite (HaP) materials 16, 42 and organic photovoltaics (OPV) 43.
