Rare Earth Solar Panels

Neodymium is a so called rare earth element a silvery metal with a very important role.

Rare earth solar panels.

A new report by the french environment and energy management agency reveals some surprises about the use of rare earth minerals in the renewable energy sector. Solar photovoltaics are made with a number of parts the most important of which are silicon cells silicon atomic number 14 on the periodic table is a nonmetal with conductive properties that give it the ability to convert sunlight into electricity. Environmental scientists and solar industry leaders are raising the red flag about used solar panels which contain toxic heavy metals and are considered hazardous waste. 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.

By depleting earth of its resources solar energy is not sustainable as the components required are limited. Mining for rare metals is considered to be one of china s most polluting industries presenting potential disasters relating to contamination that threaten to cause a wide scale catastrophe. Revision of solar panel production process. Mono vs poly vs thin film.

These compounds which are highly toxic when mined and processed also take a heavy environmental toll on soil and water. Are rare earths used in solar panels. 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. More clean energy means more solar panels wind turbines electric vehicles and large scale batteries.

In 2011 the average price of rare earth metals shot up by as much as 750 percent. How are solar panels made. Rare metals are especially vital for renewable energy technologies such as electric cars and solar panels. With recycling expensive.
