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, dating back to 2010, that Alta Devices has achieved this record. This milestone represents the thirteenth cell or module solar efficiency world record achieved by Alta Devices.

Alta Devices CEO, Jian Ding, commented, "NASA's interest in Alta's record-setting performance demonstrates that our technology withstands some of the most challenging environments endured by autonomous systems in space, high altitude, and on land. Our continued commitment to innovation enables Alta to remain an industry leader in producing state-of-the-art lightweight, flexible, and highly efficient solar cells."

According to NASA scientists, "The High Efficiency, Low-Mass Solar Cell Systems experiment exposes candidate solar cells to the space environment. In addition, thin polymeric films, developed as cover slide materials for these solar cells, are exposed as separate samples, to measure atomic oxygen erosion yield and transmission changes due to ultraviolet radiation. The test results will be especially important for the design of small but highly capable spacecraft needed to explore our solar system."
