Rocket Lab Announces New Germanium-Free Solar Cell for Satellites
Rocket Lab (RKLB) unveiled a new solar cell called IMM Apex, designed to power satellites more efficiently and with reduced weight. The product is notable because it eliminates the use of germanium, a material primarily sourced from China, which has been a concern in global supply chains due to geopolitical tensions. The company claims the new cells offer 31.5% efficiency while weighing 40% less than previous models and can be used as direct replacements without redesigning spacecraft. Rocket Lab's solar technology heritage includes powering NASA’s Ingenuity Mars helicopter, the James Webb Space Telescope, and Artemis lunar missions. The company acquired SolAero Technologies in 2022 to bolster its capabilities in this area. Despite a positive initial market reaction on news of the innovation, Rocket Lab shares fell by nearly 4% following broader declines across space stocks linked to a SpaceX share unlock. Analysts remain optimistic about Rocket Lab’s prospects, with an average price target suggesting significant upside potential from current levels.
