- Why Use Gallium Arsenide Solar Cells?
Welcome back to planet earth, GaAs! Thus, more energy is captured where it would have been lost using traditional solar technology.
Innovation Starts Here.
Continuous Innovation At Alta Devices we gallium arsenide solar cells constantly looking for ways to improve our product line. Our first generation products, introduced indemonstrated our ability to mass produce the highest efficient and thinnest single junction solar cell on the market.
Good Low Light Performance: In most solar cells, the energy available in weak illumination low light leaks away, but not in high quality GaAs.
The wide bandgap and low-defect crystal structure also results in a lower leakage current and more rapid voltage buildup with illumination. The wider bandgap of GaAs also means it is much better tuned to the gallium arsenide solar cells of LED and fluorescent light, relative to silicon.
Alta Devices makes the world's most efficient solar cells.
So even in an office or warehouse environment, solar power can be generated using GaAs. In addition, a Si crystal has a very stable structure and can be grown to very large diameter boules and processed gallium arsenide solar cells very good yields.
It is also a fairly good thermal conductor, thus enabling very dense packing of transistors that need to get rid of their heat of operation, all very desirable for design and manufacturing of very large ICs.
Such good mechanical characteristics also make it a suitable gallium arsenide solar cells for the rapidly developing field of nanoelectronics.
Gallium arsenide - Wikipedia
Naturally, GaAs surface cannot withstand the high temperature needed gallium arsenide solar cells diffusion; however a viable and actively pursued alternative as of the s was ion implanation. Silicon dioxide can easily be incorporated onto silicon circuits, and such layers are adherent to the underlying silicon.
SiO2 is not only a good insulator with a band gap of 8. GaAs does not have a native oxide, does not easily support a stable adherent insulating layer, and does not possess the dielectric strength or surface passivating qualities of the Si-SiO2.
gallium arsenide solar cells
Because they lack a fast CMOS structure, GaAs circuits must use logic styles which have much higher power consumption; this has made GaAs logic circuits unable to compete with silicon logic circuits. The quasi-Fermi level splitting is of great interest since it is directly related to the maximum achievable voltage of gallium arsenide solar cells cell and to the saturation currents.
