What are Cadmium Telluride Solar Cells? (2024)
Cadmium Telluride (CdTe) is a second-generation solar cell used in thin solar panel technology that maximizes the efficiency of converting solar radiation into electricity.
Cadmium Telluride (CdTe) is a second-generation solar cell used in thin solar panel technology that maximizes the efficiency of converting solar radiation into electricity.
CdTe is already a success story. It supplies 40% of the U.S. utility-scale photovoltaic (PV) market and 5% of the world market. It is competing successfully with imported silicon. And it is the only scaled
PV solar cells based on CdTe represent the largest segment of commercial thin-film module production worldwide. Recent improvements have matched the efficiency of multicrystalline
Semiconductor materials ranging from “micromorphic and amorphous silicon” to quaternary or binary semiconductors such as “cadmium telluride (CdTe) and
This work was authored in part by the National Renewable Energy Laboratory, operated by Alliance for Sustainable Energy, LLC, for the U.S. Department of Energy (DOE) under Contract No. DE-AC36
DOE supports innovative research focused on overcoming the current technological and commercial barriers for cadmium telluride (CdTe) solar cells.
OverviewMaterialsBackgroundHistoryTechnologyRecyclingEnvironmental and health impactMarket viability
Cadmium (Cd), a toxic heavy metal considered a hazardous substance, is a waste byproduct of mining, smelting and refining sulfidic ores of zinc during zinc refining, and therefore its production does not depend on PV market demand. CdTe PV modules provide a beneficial and safe use for cadmium that would otherwise be stored for future use or disposed of in landfills as hazardous waste. Mining byproducts can be converted into a stable CdTe compound and safely encapsulated inside CdTe PV s
The second generation (Gen II) of solar PV technology is also known as “conventional” thin films. It is specifically addressed as CdTe, amorphous silicon (a-Si), and copper indium gallium
Cadmium and tellurium form a stable semiconductor compound, CdTe, that is used in thin-film photovoltaic (PV) cells. CdTe PV cells are used in some of the
