Do Solar Panels Use Rare Earth Minerals

In 2011 the average price of rare earth metals shot up by as much as 750 percent.

Do solar panels use rare earth minerals.

They are often found in minerals with thorium th and less commonly uranium u. The new photovoltaic technology uses abundant less expensive materials like copper and zinc earth abundant materials instead of indium gallium and other so called rare earth elements. Recent advances in rare earth elements modification of inanic solar cells rare earth metals what are rare earth metals for kazspecgeology requirements for mineraletals 100 renewable scenarios how to make solar panels last longer mining. This means that global production of several rare earth minerals used.

Using rare metals in solar panels. A scarcity of rare metals is hindering green technologies yale e360. And panels can contain toxic materials or rare earth elements mined in war torn countries so called conflict minerals. Thin cheap solar panels need tellurium which makes up a scant 0 0000001 percent of the earth s crust making it three times rarer than gold.

These can include magnetic neodymium electronic indium. Manufacturing those products consumes energy and water and emits greenhouse gases. To meet greenhouse gas emission reduction targets under the paris agreement renewable energy production has to scale up fast. 97 of solar panels are silicon based.

Plenty of high tech electronic components like solar panels rechargeable batteries and complex circuits require specific rare metals. What are rare earth metals for kazspecgeology. While solar panels generate carbon free electricity they carry environmental footprints of their own. Notice no rare earth metals in any type of commercial solar panel.

Experts have found that the rare metals required to build solar panels such as indium and tellurium are not in sufficient supply to keep up with demand. High performance batteries need lithium which is only easily extracted from briny pools in the andes. A new report by the french environment and energy management agency ademe shows that rare earth minerals are not widely used in solar energy and battery storage technologies.
