Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is mainly used as the semiconducting material in cadmium telluride photovoltaics and an infrared optical window. It is usually sandwiched with cadmium sulfide to form a p–n junction solar PV cell.
Cadmium telluride PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems. [ 1 ] [ 2 ] [ 3 ] On a lifecycle basis, CdTe PV has the smallest carbon footprint , lowest water use and shortest energy payback time of any current photovoltaic technology.
Cadmium sulfide: CdS: 2.42 [6] direct: Used in photoresistors and solar cells; CdS/Cu 2 S was the first efficient solar cell. Used in solar cells with CdTe. Common as quantum dots. Crystals can act as solid-state lasers. Electroluminescent. When doped, can act as a phosphor. II-VI: 2: Cadmium telluride: CdTe: 1.49 [6] direct: Used in solar ...
Mercury cadmium telluride is known to be a toxic material, with additional danger from the high vapor pressure of mercury at the material's melting point; in spite of this, it continues to be developed and used in its applications.
First Solar uses rigid thin-film modules for its solar panels, and produces CdTe panels using cadmium telluride (CdTe) as a semiconductor. [3] The company was founded in 1990 by inventor Harold McMaster as Solar Cells, Inc. and the Florida Corporation in 1993 with JD Polk. In 1999 it was purchased by True North Partners, LLC, who rebranded it ...
Cadmium tellurite is a colourless solid [1] that is insoluble in water. [2] It is a semiconductor. It is part of the monoclinic crystal system, with space group P2 1 /c (No. 14). It can also crystallize in the cubic crystal system and hexagonal crystal system at temperatures above 540 °C. [4] [5]
Monocrystalline solar cell This is a list of notable photovoltaics (PV) companies. Grid-connected solar photovoltaics (PV) is the fastest growing energy technology in the world, growing from a cumulative installed capacity of 7.7 GW in 2007, to 320 GW in 2016. In 2016, 93% of the global PV cell manufacturing capacity utilized crystalline silicon (cSi) technology, representing a commanding lead ...
Cadmium telluride (CdTe) is one of the fastest-growing thin film based solar cells which are collectively known as second-generation devices. This new thin-film device also shares similar performance restrictions ( Shockley-Queisser efficiency limit ) as conventional Si devices but promises to lower the cost of each device by both reducing ...
