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 means that it can produce nearly twice as much power in a given surface area.
Like conventional solar panels amorphous solar panels are made from silicon but they are constructed in a different way.
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.
These advantages are important factors that can be applied to automotive design and manufacturing.
Gallium arsenide gaas is the highest performance solar material currently available boasting conversion efficiencies in excess of 40 nearly double those of crystalline silicon.
In a recent article in the magazine electronic news gallium arsenide was tested on a germanium substrate.
The first known operational use of gaas solar cells in space was for the venera 3 mission launched in 1965.
This makes them a good candidate for a stacked type of solar panels used for collecting light from all across the spectrum.
