Advantage of tellurium in solar panels.

Solar cells based on cadmium and tellurium could move closer to theoretical levels of efficiency because of some sleuthing by researchers at the department of energy s oak ridge national laboratory. With efficiencies exceeding 20 measured in the laboratory there may be a continuing place for high efficiency cigs panels in the general solar panel market. Cadmium telluride cdte photovoltaics describes a photovoltaic pv technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. That s right adding solar photovoltaic panels on the roof of your home is going to save you tons of money.

The last 10 years have seen huge developments in the world of solar. The major advantage of this technology is that the panels can manufactured at lower costs than silicon based solar panels. First solar was the first manufacturer of cadmium telluride panels to produced solar cells for less than 1 00 per watt. Cadmium telluride is a direct bandgap material with bandgap energy of about 1 45 defined ev which is well matched to the solar spectrum and nearly optimal for converting sunlight into electricity using a single junction.

Solar energy drawbacks tellurium a rare metal found the bottom of an undisturbed part of an ocean and extracting it can be a dangerous process as it is considered whether it is worth the risk to disturb the depths of the ocean without affecting its ecosystem. The benefits of cdte thin film solar cells include. Homeowners are interested in solar panels but haven t taken the time to figure out what it takes to install them. Unlike most thin film solar technologies cigs solar panels offer a potentially competitive efficiency to traditional silicon panels.

Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems. Going off grid is a huge advantage of solar power for people in isolated locations. This consumer reality and the undeniable benefits of having solar panels on a home complements recent studies that found property values increase after solar is installed. In the coming years these markets are.

On average over 20 years you re likely to save up to or over 20 000 and even more if you live in particularly sunny or populous states where energy costs are higher. Solar improves the value of your home. 1 solar saves you money. Tellurium is essential to several different modern technologies such as solar panels and thermoelectric generators which make up 70 of tellurium demand.
