Rare Materials In Solar Panels

As such solar panels require way more raw materials including glass rare earth elements and heavy metals than other energy sources.

Thin film pv technologies for example contain potentially critical metals such as tellurium. 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. In 2011 the average price of rare earth metals shot up by as much as 750 percent.

Cadmium telluride cadmium solar cells are the only thin film product to have rivaled the performance of. Amorphous silicon this is a popular material used widely on thin film solar cells. So why the interest in rare earth. Here are the common parts of a solar panel.

Silicon solar cells metal frame typically aluminum glass sheet for casing standard 12v wire bus wire plexiglas. For example a single tesla vehicle requires about 15 pounds or a bowling ball s worth of lithium and thin cheap solar panels need tellurium one of the rarest elements on earth. 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. Rare metals are especially vital for renewable energy technologies such as electric cars and solar panels.

Unfortunately you can t just put the panels out with your. 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. It uses around 1 of the silicon. Neodymium is a so called rare earth element a silvery metal with a very important role in renewable energy.

High performance batteries need lithium which is only easily extracted from briny pools in the andes. When combined with iron and boron it makes strong magnets that are important both for.
