Gaas Solar Panel

Like conventional solar panels amorphous solar panels are made from silicon but they are constructed in a different way.

Gaas solar panel.

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 gaas is the highest performance solar material currently available boasting conversion efficiencies in excess of 40 nearly double those of crystalline silicon. This means that it can produce nearly twice as much power in a given surface area. These advantages are important factors that can be applied to automotive design and manufacturing.

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. Gallium arsenide solar cells can have roughly 25 efficiency rating with only one junction. Unlike traditional solar panels gallium arsenide thin film solar cells have the advantages of flexibility flexibility light weight adjustable color and shape plasticity.
