Alta Devices disclosed that it has reached 30.8% solar cell efficiency. This new
NREL (National Renewable Energy Laboratory) verified record has resulted from the
company’s first implementation of a new generation “dual junction” solar cell technology.
One which also augments the company’s “single junction” technology.

Higher efficiency directly translates into more electricity generated from smaller
surface areas. Therefore, applying Alta’s highly efficient, very thin and flexible
mobile power technology to consumer devices can extend the battery life of everyday
products such as smartphones, tablets, keyboards, mice, remote controls, and more.

“We are changing the way solar technology is used,” said Chris Norris, president
and CEO of [Alta Devices](https://greenlivingguy.com/2017/08/audi-partners-with-alta-devices-to-use-leading-solar-technology-on-new-cars/).“
With our technology, enough energy can be generated from sunlight to effectively
power devices in ways not previously possible. We are working with a number of customers
who are designing their mobile products to increase battery life; and in some cases,
we can provide enough energy to eliminate the need to plug into the electric grid.”

### Will Enable Significant Battery Life Extension in Mobile and Consumer Devicesa

To help device manufacturers understand the benefits of using Alta’s material on
their products, Alta has created a calculator to compute the battery life extension
for a variety of consumer mobile devices. According to the calculator, a typical
outdoor worker could realize 80 percent more battery life. That’s most notably each
day for their mobile phone. Or a student can get over 60 percent more battery life
for his or her tablet device. These results can be achieved with minimal weight 
or form–factor penalty on the device design.

### Alta’s Second Generation Technology

“Alta Devices has been setting efficiency records since 2010. This new dual junction
record at 30.8% is a testament to our technology and our world–class team. It’s 
also an important step toward our target of 38% efficient cells,” said Norris. “
We continue to redefine the boundaries of what is possible with solar power.”

Alta Devices finally have pioneered the world’s highest efficiency single junction
solar technology. That’s clearly by using a number of breakthrough approaches. Especially
to implementing Gallium Arsenide (GaAs) for solar cells. The company’s new dual 
junction technology builds on that basic GaAs approach. However, it implements a
second junction (or layer) with Indium Gallium Phosphide (InGaP). Especially as 
the absorber on top of the base cell. Because InGaP uses high-energy photons more
efficiently. Then the new dual junction cell generates more electricity. Especially,
the same amount of light than a single junction device. Alta Devices is also currently
shipping its single junction technology.
