Tellurium Solar Panel

Cadmium telluride solar cells the united states is the leader in cadmium telluride cdte photovoltaic pv manufacturing and nrel has been at the forefront of research and development in this area.

Tellurium solar panel.

Of all the solar technologies cdte solar panels are the most. Cadmium telluride is one of the second generation thin film solar cell technologies. 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. 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.

Tellurium is essential to several different modern technologies such as solar panels and thermoelectric generators which make up 70 of tellurium demand. The main concern surrounding tellurium supply is the question of whether or not global copper production can meet the growth in tellurium demand. A layer of cadmium telluride just one thousandth of a millimetre thick will absorb around 90 of the light that hits it. Tellurium alloyed with cadmium forms the compound cadmium telluride cdte a highly conductive compound when exposed to sunlight.

Cadmium telluride thin film solar cells are providing a lower cost alternative to conventional silicon based solar panels. Pv solar cells based on cdte represent the largest segment of commercial thin film module production worldwide. According to a report published by techsci research on global solar panel recycling market the global solar panel recycling market is projected to grow at a cagr of around 20 through 2024 on the back of increasing volume of decommissioned pv panels coupled with strict laws to boost effective recycling. Cadmium telluride pv is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi kilowatt systems.

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. 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. In the coming years these markets are.
