Alta Devices uses Gallium Arsenide (GaAs) as the basis for our solar technology. It’s a lesser known material so we wanted to share some key information here: What is Gallium Arsenide? Gallium Arsenide (GaAs) is a semiconductor material and a compound of Gallium and Arsenic (interconnected cubic lattices). Traditionally it’s an expensive material mostly used…
NASA is testing Alta Devices solar technology at the International Space Station in order to evaluate Alta’s technology for future NASA low-Earth orbit missions, including powering CubeSats. Alta Devices also recently announced a new efficiency record of 29.1% for its single junction solar cell, as certified by Fraunhofer ISE CalLab, marking the seventh consecutive time,…
WASHINGTON, At AUVSI, August 12, 2013 – AeroVironment, Inc. (NASDAQ:AVAV) today announced that a recent outdoor test flight of a solar-powered prototype version of the company’s proven Puma AE™ small unmanned aircraft system (UAS), operating with the company’s newest long-endurance battery, lasted 9 hours, 11 minutes – significantly longer than the flight endurance of small…
Sunnyvale, CA – March 4, 2013 – 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…
Aircraft that fly at stratospheric altitudes are an important new category that include: These aircraft are designed to extend connectivity to people around the world in remote locations, under served areas or after natural disasters. Solar is a critical factor in enabling these aircraft to remain aloft for periods of multiple weeks or years. Alta…
