UAV lift-off: Will 31.6 percent solar energy efficiency record breaker prove critical?

Alta Devices has achieved a 31.6% solar energy efficiency record which could drive to changes in the fundamental economics of operating Unmanned Aerial Vehicles.

Alta believes that the combined thinness and flexibility of the solar cell design will help redefine how solar technology can be used. Alta’s solar technology is attracting interest in the UAV (unmanned aerial vehicle) market. The increased power-to-weight ratio of Alta’s technology enables different possibilities for an aircraft using the solar cell technology compared with any of the other solar power options.
