Rare Earth Materials Used In Solar Panels

Plastic plastic is a common feature of a solar panel.

Rare earth materials used in solar panels.

In 2011 the average price of rare earth metals shot up by as much as 750 percent. Pure silicon is crystalline a structure necessary for photovoltaic cells. Terbium and europium are used in thin film solar panels while dysprosium is used to manufacture batteries in most hybrid gas electric vehicles. These can include magnetic neodymium electronic indium.

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. 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 hinder a 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. When combined with iron and boron it makes strong magnets that are important both for.

Neodymium is used in wind turbines and hybrid cars. 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. The metallurgical grade silicon is exposed to hydrochloric acid and copper which produce trichlorosilane gas. It can be used to house junction boxes that are often found on the underside of a solar panel.

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. Hydrogen is then used to reduce this gas to silane gas which is in turn heated to make molten silicon.
