6 FAQs about [GaAs solar power generation principle]

What is a GaAs solar cell?

The GaAs solar cells can be tuned into layering applications, they can split into eight thin layers from a single solar cell . In comparison to silicon cell technology, this GaAs solar cell can form thin films, has a better heat coefficient, is radiation resistant, and can be converted into a multijunction solar cell.

How efficient are GaAs solar cells?

We have measured all the GaAs cells properly fabricated on 2 inch wafer. The efficiency was slightly varied from cell to cell over the whole wafer but the most of cells exhibit efficiencies of more than 21% and the minimum efficiency was at least 20.84%. Thus, these highly efficient GaAs solar cells are reliably demonstrated.

Can a GaAs solar cell generate more current than a Si solar cell?

Without constraint, the GaAs solar cell would generates almost twice the current of the Si solar cell in the stack. Current matching can be achieved either with a very thin top cell or by area matching , . Given the disparity in current generation, in previous reports we concentrated on the four-terminal architecture.

How do GaAs-based solar cells work?

For GaAs-based solar cells, performance can also be tuned by layering, where one solar cell can contain up to eight thin layers, each absorbing light at a specific wavelength. Such photovoltaic cells are called multi-junction or cascade solar cells. They use tandem fabrication, so they can also be found under the name tandem cells.

Why are GaAs solar cells used in high electron mobility transistors?

GaAs solar cells are very popular in high electron mobility transistor structures because it does not have required any momentum change in valence and conduction band. The GaAs solar cells can be tuned into layering applications, they can split into eight thin layers from a single solar cell .

Why are GaAs solar cells so popular?

The interest in GaAs solar cells has become more popular in the recent years due to its band gap (1.42 ev) close to the standard spectrum . However, its major problem was the surface recombination rate that has been reducing the GaAs solar cells improvement’s start with 10% .
