Tellurium Solar Panel

Of all the solar technologies cdte solar panels are the most.

Tellurium solar panel. Cadmium telluride thin film solar cells are providing a lower cost alternative to conventional silicon based solar 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. Cadmium telluride cdte solar panels as the second most common photovoltaic technology on the market behind traditional crystalline silicon cadmium telluride cdte panels are already a viable thin film solar panel solution. Pv solar cells based on cdte represent the largest segment of commercial thin film module production worldwide.

Tellurium is essential to several different modern technologies such as solar panels and thermoelectric generators which make up 70 of tellurium demand. Cadmium telluride cdte photovoltaics or also called cadmium telluride solar cell is a kind of photovoltaic pv technology that can produce electricity from sunlight using a thin film of compound cadmium telluride to absorb and convert sunlight into electricity. It s far better at absorbing light than silicon on which most solar power is currently based and as a result its absorbing layer doesn t need to be as thick. The main concern surrounding tellurium supply is the question of whether or not global copper production can meet the growth in tellurium demand.

Tellurium alloyed with cadmium forms the compound cadmium telluride cdte a highly conductive compound when exposed to sunlight. In the coming years these markets are. Demands for tellurium particularly as the global carbon footprint is reduced and solar energy technology becomes more widespread are predicted to increase steadily over the next 15 to 20 years. On a lifecycle basis cdte pv has the smallest carbon footprint lowest water use and shortest energy payback time of any current photo voltai.

A layer of cadmium telluride just one thousandth of a millimetre thick will absorb around 90 of the light that hits it. Cadmium telluride photovoltaics describes a photovoltaic technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. Extremely rare yet a vital ingredient to emerging solar panel technologies tellurium is the epitome of what it means to be a critical metalloid an element that possesses the properties of both a metal and non metal.
