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.
Rare earth elements in solar panels.
High performance batteries need lithium which is only easily extracted from briny pools in the andes.
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.
However a lack of rare earths does not mean that the components of solar modules are harmless.
Rare earth metals hard to find materials with unfamiliar names such as lanthanum neodymium and europium are used in wind and solar energy projects but dwindling supplies could hindera roll out of low carbon technologies and slow china s shift away from coal power.
Neodymium is a so called rare earth element a silvery metal with a very important role in renewable energy.
Rare metals are especially vital for renewable energy technologies such as electric cars and solar panels.
However recent research coming out of the netherlands has spotted a red flag to relying on solar panels as a panacea for global emissions problems.
This means that global production of several rare earth minerals used in solar panels and wind turbines especially neodymium terbium indium dysprosium and praseodymium must grow twelvefold by.
For example a single tesla vehicle requires about 15 pounds or a bowling ball s worth of lithium and thin cheap solar panels need tellurium one of the rarest elements on earth.
Rare earth elements are 17 elements found on earth.

July 2 2019 solar panels wind turbines and electric car batteries are made from some of the most hard to get metals on earth dysprosium neodymium manganese cobalt and lithium.
Thin film pv technologies for example contain potentially critical metals such as tellurium.
