Unlike traditional solar panels gallium arsenide thin film solar cells have the advantages of flexibility flexibility light weight adjustable color and shape plasticity.
Gaas solar panel.
This makes them a good candidate for a stacked type of solar panels used for collecting light from all across the spectrum.
Gallium arsenide gaas is the highest performance solar material currently available boasting conversion efficiencies in excess of 40 nearly double those of crystalline silicon.
The first known operational use of gaas solar cells in space was for the venera 3 mission launched in 1965.
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.
Gallium arsenide solar cells can have roughly 25 efficiency rating with only one junction.
This means that it can produce nearly twice as much power in a given surface area.
In a recent article in the magazine electronic news gallium arsenide was tested on a germanium substrate.
Instead of being constructed from solid silicon wafers like mono or poly crystalline solar panels amorphous panels are made by depositing non crystalline silicon on a substrate like glass plastic or metal one layer of silicon on an amorphous solar panel can be as thin.
