Copper is the new silver lining

As the PV industry scales to annual terawatt-level production to rapidly curtail the world’s emissions, it will become more challenging to continue the cost reduction trajectory. Increasing module production from current levels of 200 GW to 300 GW to several terawatts each year will consume significantly more material resources than the industry currently uses. This will require consideration of the additional materials to be sourced, writes Alison Lennon, chief scientist at Sundrive Solar and professor at the UNSW’s School of Photovoltaic and Renewable Energy Engineering.
