Gallium Arsenide Solar Panel Efficiency

For example a solar panel with 20 efficiency and an area of 1 m 2 will produce 200 kwh yr at standard test conditions but it can produce more when the sun is high in the sky and will produce less in cloudy conditions or when the sun is low in the sky.

Gallium arsenide solar panel efficiency.

The best monocrystalline solar cells on the market today can reach an efficiency of about 26 10. Filling a market gap. Taken together they are the largest representation of solar in space occupying enough area to cover most of a football field. The record was independently confirmed by the national renewable energy laboratory part of the department of energy.

Gaas solar cells can harness more sunlight than silicon based solar cells because they are made using a soft and silvery metal which can also be found in electronic circuits semiconductor materials and light emitting diodes. Gallium arsenide solar cells. As a runner up multi junction cells made of gallium arsenide and similar materials resist degradation better than silicon and are the most efficient cells currently made with energy conversion efficiencies up to 34. One of the great advantages of gallium arsenide is that the theoretical efficiency is high almost twice as high as that of crystalline silicon.

The same company has now set an efficiency record for an entire solar panel at 23 5 percent. Gallium arsenide solar cells can have roughly 25 efficiency rating with only one junction. Solar cells and detectors gallium arsenide is an important semiconductor material for high cost high efficiency solar cells and is used for single crystalline thin film solar cells and for multi junction solar cells. This makes them a good candidate for a stacked type of solar panels used for collecting light from all across the spectrum.

This is a superior property of gallium arsenide. 10cm x 15cm shown above next to a business card. However this technology is some of the most expensive solar tech. Actual size of a 2kw gallium arsenide super cell is approx.

The first known operational use of gaas solar cells in space was for the venera 3 mission launched in 1965. Gallium arsenide multi junction and other advanced technologies could be the next generation. The resulting efficiency level was 24 9 for a single junction. Adding that one layer of the gallium arsenide phosphide can really boost efficiency of the solar cell but because of the unique ability to etch away the silicon germanium and reuse it the cost is kept low because you can amortize that silicon germanium cost over the course of manufacturing many cells fitzgerald adds.

In a recent article in the magazine electronic news gallium arsenide was tested on a germanium substrate. Alta devices makes solar panels using gallium arsenide cells a more efficient material than the generally cheaper silicon based cells. A solar panel s efficiency how effective a panel is at converting sunlight into electricity is a key factor determining solar panel quality and manufacturers are constantly improving their processes to create higher efficiency solar panels.
