This Startup Makes Solar Much Much Cheaper With A Particle Acclerator

Categories: Tech, Energy

The cost of solar panels is dropping exponentially, and solar power is now 80% cheaper than it was in 2010. A new startup plans to make it even more of a threat to fossil fuels, while also making panels much more efficient.

Using a particle accelerator—a machine that speeds up sub-atomic particles to nearly the speed of light—Rayton Solar slices up ultra-precise pieces of silicon, the key material used to make most solar panels. In typical manufacturing, a clunky cutting process wastes much of the material. When making a 200 micron-thick wafer of silicon, another 200 microns of the material ends up as sawdust.

The new patented process eliminates that waste. "Once you have a certain energy level of the particle and you shoot it at a block of silicon, it will penetrate at a certain depth into that silicon," says Andrew Yakub, Rayton Solar's 29-year-old CEO. "That's how we do our cutting at such a precise depth."

By preserving the material, Rayton is able to use higher-quality silicon—something that wasn't economical for companies to do in the past. The new panels are 25% more efficient. That leads to a reduction in other costs—less land is needed, and less other equipment. And the panels themselves are also 60% cheaper to manufacture.

That dramatic drop in cost could help the solar industry grow much faster than it already is. Rayton has proven the process in the lab, and is currently running an equity crowdfunding campaign to build a pilot manufacturing line (it plans to do this in the U.S.; the low cost of the new process makes it economical to build here). Then it plans to quickly scale.

"Solar has hit the threshold where it's just about become the cheapest source of energy," says Yakub. "It's coming to a crossroads, and with a slight technological improvement like this, it will push it over the threshold that welcomes a worldwide solar transformation. We see this happening with or without Rayton's technology, but our technology will speed it up significantly."

It's something that will happen, he says, whether or not the next administration supports renewable energy. "In regards to Trump, I see him not having an effect on the solar industry," he says. "Because the economics are there. If the economics are there, the natural market forces will take control. I don't see it as something that the government can have much control of."

"I see a future where you can pop open a solar umbrella, and power your RV.  Ready or not, here comes the energy!"
