6 FAQs about [CdTe solar cell power generation principle]
What is a CdTe solar cell?
CdTe is a material made from the combination of two elements: Cadmium (Cd) and Tellurium (Te). It plays a critical role of light absorption—hence why a CdTe solar cell is named after it. However, a cell needs more than just the CdTe material to function. CdTe is a material made from the combination of two elements: Cadmium (Cd) and Tellurium (Te).
How are CdTe solar cells produced?
Usually, CdTe solar cells are produced on a glass substrate with a pre-deposited thin transparent conducting surface. This is one reason that these cells are inexpensive to produce. A thin (∼ 100 nm) polycrystalline (poly)-CdS layer is deposited on a glass/TCO (thin conducting oxide) stack, followed by the deposition of a ∼ 4 μm poly-CdTe layer.
How efficient is a CdTe solar cell?
The maximum theoretical efficiency of the CdTe solar cell corresponding to a band gap of 1.5 eV is about 28%–30%. CdTe has long been known as a leading thin film photovoltaic material due to its near optimal direct bandgap of 1.44 eV and high absorption coefficient.
What are PV solar cells based on CdTe?
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 silicon while maintaining cost leadership.
Can CdTe based solar cells be made on other substrates?
In thin film technologies, buffer layers were introduced to attempt to make lower-recombination interfaces with the absorber. CdTe-based solar cells have been made on other substrates such as steel or polymers in laboratories, but these approaches have yet to be commercialized.
Are CdTe solar systems competitive with other forms of solar energy?
Recent installations of large First Solar CdTe PV systems were claimed to be competitive with other forms of solar energy: First Solar's 290- megawatt (MW) Agua Caliente project in Arizona is one of the largest photovoltaic power station ever built.
