US solar technology manufacturer Alta Devices has achieved a conversion efficiency of 29.1% with its gallium arsenide cell, beating its previous record of 28.9% announced in June. Alta's cells are also being tested by NASA on the International Space Station after the company, a Hanergy Group subsidiary, was selected to be part of November's Materials International Space Station Experiment flight investigation. The cells will be returned to NASA and Alta in a year's time for evaluation.
