Rare Materials In Solar Panels
Thin film pv technologies for example contain potentially critical metals such as tellurium.
Rare materials in solar panels. Cadmium telluride cadmium solar cells are the only thin film product to have rivaled the performance of. Terbium and europium are used in thin film solar panels while dysprosium is used to manufacture batteries in most hybrid gas electric vehicles that use magnets. 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. Here are the common parts of a solar panel.
The most popular materials in thin film solar cells are as follows. When combined with iron and boron it makes strong magnets that are important both for. Amorphous silicon this is a popular material used widely on thin film solar cells. It uses around 1 of the silicon.
So why the interest in rare earth. In 2011 the average price of rare earth metals shot up by as much as 750 percent. 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. 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.

However a lack of rare earths does not mean that the components of solar modules are harmless. Rare metals are especially vital for renewable energy technologies such as electric cars and solar panels.
