Plastic plastic is a common feature of a solar panel.

Rare earth materials used in solar panels.

It can be used in everything from wires including earthing cables through to inverters that convert dc current to ac. When combined with iron and boron it makes strong magnets that are important both for. High performance batteries need lithium which is only easily extracted from briny pools in the andes. Neodymium is used in wind turbines and hybrid cars.

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. The metallurgical grade silicon is exposed to hydrochloric acid and copper which produce trichlorosilane gas. In 2011 the average price of rare earth metals shot up by as much as 750 percent. It can be used to house junction boxes that are often found on the underside of a solar panel.

Plenty of high tech electronic components like solar panels rechargeable batteries and complex circuits require specific rare metals. Terbium and europium are used in thin film solar panels while dysprosium is used to manufacture batteries in most hybrid gas electric vehicles. Copper you can find copper in various components of a solar panel. 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.
