Gallium Arsenide Solar Panels

In a recent article in the magazine electronic news gallium arsenide was tested on a germanium substrate.

Gallium arsenide solar panels.

There the main cost is launching the satellite into. Gallium arsenide solar cells. Plan your solar panel system carefullyplace the square solar cells onto the wooden board and draw separating lines carefully. 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.

It has a bandgap of 1 49 ev which is better than silicon. Junction refers to the number of light absorbing layers in the cell. Then there s the landfill legacy being created by wind turbine blades with the first world cynically using the. It s a compound mixture of gallium and arsenic.

Gallium arsenide super efficient solar cells. It would certainly be nice being energy independent let alone having an. These advantages are important factors that can be applied to automotive design and manufacturing. Gallium arsenide solar cells can have roughly 25 efficiency rating with only one junction.

Just make sure your ammeter bears the solar cells nominal power 108w at 12v means 9 amps. This world record was set by dr mark keevers and professor martin green senior research fellow and director respectively of unsw s australian centre for advanced photovoltaic s using a 28 square centimetre four. The resulting efficiency level was 24 9 for a single junction. Unlike traditional solar panels gallium arsenide thin film solar cells have the advantages of flexibility flexibility light weight adjustable color and shape plasticity.

It s highly effective as a semiconductor and produces a high energy yield for a small amount of material. But silicon based solar is so much cheaper to make that gallium arsenide solar cells are relegated to exotic applications such as satellites. Gallium arsenide gaas has been growing in popularity as a solar panels semiconductor in recent years. This makes them a good candidate for a stacked type of solar panels used for collecting light from all across the spectrum.

The first known operational use of gaas solar cells in space was for the venera 3 mission launched in 1965. 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.
