How can a dynamic material flow analysis improve PV solar technology?

The analysis carried here could be enhanced by including either dynamic material flow analysis bottom-up or top-down approaches for the metals used in the PV solar technologies. This would allow for estimating the future demand for these metals not only for PV solar technologies but also for other applications.

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.

What is a photovoltaic (PV) market?

1. Introduction Driven by rapid cost reduction, photovoltaic (PV) is a fast-growing market that reached a global capacity of 627 GW p at the end of 2019, sufficient to meet around 3% of global electricity demand [ 1 ].

What is a photovoltaics value chain?

Similarly to any other industry, the photovoltaics value chain can be broken down into several specific types of organizations (supplier, operators, consulting firms) that actually operate the various processes involved into the value chain. First, there is a whole series of products that are required to build a PV solar systems.

Why do we need new materials for solar photovoltaic systems?

Furthermore, the growing need for renewable energy sources and the necessity for long-term energy solutions have fueled research into novel materials for solar photovoltaic systems. Researchers have concentrated on increasing the efficiency of solar cells by creating novel materials that can collect and convert sunlight into power.
