NREL Verifies Alta Devices’ Achievement of 30.8% Solar Cell Efficiency

Alta Devices today 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 which 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. “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.”

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 (http://www.altadevices.com/calculator.php). According to the calculator, a typical outdoor worker could realize 80 percent more battery life 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.
