6 FAQs about [How much indium copper can be extracted from photovoltaic panels]

What is end-of-life management of copper indium gallium selenide (CIGS) thin-film solar photovoltaic?

End-of-life management of copper indium gallium selenide (CIGS) thin-film solar photovoltaics (PV) panels is crucial due to the necessity of recycling valuable elements such as indium ($400/kg) and gallium ($618/kg), ensuring both economic viability and environmental sustainability.

Will indium production lag behind demand for photovoltaic solar panels?

Boosting this could greatly alleviate supply pressures. Projections indicate that indium production will reach its peak between 2025 and 2030, while the peak for photovoltaic solar panels due to indium shortages is anticipated around 2090, with an installed capacity of 1200 GW. Thus, the growth of photovoltaic capacity may lag behind actual demand.

How many photovoltaic technologies require indium?

Ten of these photovoltaic technologies require indium, five of them require gallium in addition to indium, three of them require antimony in addition to indium, one technology requires tellurium in addition to indium, three of them require selenium in addition to indium and six of them demand silver in addition to indium.

How does indium shortage affect the production of solar panels?

The physical indium shortage and the dependence on an unresponsive source metal extraction rate may have ramifications for the production of large volumes of solar panels for electricity generation.

What happens if a photovoltaic system delivers an indium supply?

The system delivers an indium supply (Figure 13 c) resulting in an installed photovoltaic collection capacity (Figure 13 d). Comparing the curves in Figure 13 b, d indicate what is going on: how the indium supply falls short of the indium demand by a huge amount. The demand for indium is satisfied until about 2024–2026.

Does the indium price increase enough to increase photovoltaic capacity?

The indium price does increase enough to increase the indium recycling some, but yields limitations prevail. The result shows that the photovoltaic capacity demanded is far larger than what can be realized in reality. It appears to be not enough indium available.
