Gallium Antimide Solar Cell Efficiency

GaSb solar cells have proven to be the most efficient semiconductors. The biggest drawback is pricing. GaSb high prices make the wafers unprofitable compared to silicon based solar cells. But researchers should not shy away from researching these solar cells. There may be a day when a homeowner's roof could be considered a solar commodity and higher-efficiency cells could make a smaller roof as profitable as a larger roof with silicon solar panels.

Let us know if we can quote you on GaSb and GaAs solar wafers and start your research today!

What Is the Infrared Spectrum of a Compound?

The infrared spectrum consists of bands that represents a specific functional group and are characterized by several chemical compounds. These bands help scientists determine the structure and properties of an unknown compound that they may be researching. Infrared (IR) spectroscopy can be used to identify the functional groups of gases and liquids.

Indium Gallium Antimonide Solar Cells

Indium-gallium-antimonide (GaSb) solar cells are excellent at light-trapping and absorption properties. The wafers and are particularly good in the infrared spectrum. They can also be made to use the energy from the sun's ultraviolet and infrared rays. They have several advantages over other types of silicon-based solar cells, including their high-temperature thermometers and ability to detect IR radiation.

Unlike Silicon, GaSb solar cells are much more expensive.

GaSb solar cells low resistance to heat and light extremely high thermal resistance make them a perfect fit for solar research. Their efficiency make GaSb solar cells better than indium-based solar cells.

What is the Band Gap of Gallium Antimonide

Gallium antimonide (GaSb) band gap of has the same lattice constants of other wafers in the III-V wafer group. This property makes GaSb an excellent substrate for solar cells. GaSb's energy density and efficiency of these materials makes the substrate a great, but expensive choice for solar cell applications. Gasb wafers are also used in infrared detectors and lasers. Tellerium-doped GaSb wafers can fabricat ethermal photovoltaic and microwave devices.

GaSb Band Gap is 0.7eV at -196 degC and the band edge energy is 0.8 eV at 650 degC.
