Rare earth materials used in solar panels.

Neodymium is used in wind turbines and hybrid cars. It can be used to house junction boxes that are often found on the underside of a solar panel. Hydrogen is then used to reduce this gas to silane gas which is in turn heated to make molten silicon. Copper you can find copper in various components of a solar panel.

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. Terbium and europium are used in thin film solar panels while dysprosium is used to manufacture batteries in most hybrid gas electric vehicles. 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. When combined with iron and boron it makes strong magnets that are important both for.

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. Plastic plastic is a common feature of a solar panel. In 2011 the average price of rare earth metals shot up by as much as 750 percent. Neodymium is a so called rare earth element a silvery metal with a very important role in renewable energy.

Pure silicon is crystalline a structure necessary for photovoltaic cells. It can be used in everything from wires including earthing cables through to inverters that convert dc current to ac. Plenty of high tech electronic components like solar panels rechargeable batteries and complex circuits require specific rare metals. High performance batteries need lithium which is only easily extracted from briny pools in the andes.
