OUR SOLAR PANEL TECHNOLOGY
- During silicon wafer production for solar cell use, high grade, thin-film silicon can be used to make a small number of solar panels, but the manufacturing process is lengthy, inefficient, and expensive.
- The industry standard method of cutting silicon crystalline is itself wasteful and inefficient.
- Current solar technology based on this technique and class of raw materials is not efficient enough to power EVs and other electronics for the masses.
In contrast, Rayton Solar is using advanced particle accelerator technology to develop solar cells consisting of a thin layer of gallium arsenide (GaAs)— a far more efficient super-semiconductor material— and it’s doing so at a significantly reduced cost. This will finally allow us to bring solar power to new solar applications, including cell phones, the rooftops of EVs, smart home devices, headphones, drones and more, thereby taking them completely off the grid.
RAYTON'S SOLAR CELL MANUFACTURING PROCESS
Our cutting technique allows for solar panel manufacturers to make solar panels 60% cheaper and 25% more efficient.
The implanted GaAs is bonded, annealed and exfoliated to separate the top layer of GaAs from the ingot.
The exfoliated GaAs film is fabricated to create solar cells using standard semiconductor processing including metallization, doping, and anti-reflective coating.

HOW GALLIUM ARSENIDE OUTPERFORMS SOLAR SILICON
Industry standard silicon cells have a ~17% efficiency versus gallium arsenide (GaAs) that can attain 27%+. Gallium arsenide has been used for space and military applications such as satellites but due to cost restrictions, no other applications have benefited from the superconductor’s potential. GaAs is the ideal material for single junction solar cells because its bandgap is almost optimal for solar energy conversion and high-quality GaAs crystal can be mass produced in a similar method as silicon crystal. GaAs-based solar cells have a record efficiency of 28.8%, the highest among single junction cells.
The Growing Value of US Solar Power
The global energy market is projected to grow to over $10.4 trillion by the year 2020.
Furthermore, the 2018 solar tariffs on imported panels will place an increased importance on U.S. solar cell manufacturers like Rayton Solar.
By 2040, renewables will command 60% of new capacity and 2/3 of power investment globally. In order to compete with the average solar module price in China (hovering at 0.43 cents per watt in 2016), a viable alternative is needed out of American manufacturers hoping to become a global sustainable energy player. Cheaper domestic solar panels will drive an increase in demand for solar as well as the demand for solar installations, thereby leading to job creation.
Federal energy requirements mandate an increase in the production of renewable energy (solar, wind, tidal, and others), and California has set their renewable portfolio standards to 1/3 of its energy portfolio by 2020.
Rayton Solar is uniquely positioned to be an industry leader as these trends continue across the country and around the world, creating the perfect legislative environment for its growth, as the global population is primed to surpass 7.5 billion people.
