US-made perovskite tandem solar cells from Swift Solar, with record efficiencies of 34.8% achieved in 2025, were recently used in a US Department of Defense cybersecurity demonstration, marking a significant milestone in their operational deployment. These modular microgrids, integrated with perovskite solar cells, offer quick setup and relocation capabilities for disaster response, military operations, and remote power generation. By depositing a thin layer on top of conventional silicon-based solar cells, perovskite tandems can boost electricity production by up to 30%, outperforming traditional silicon cells. With exclusive IP and funding, Swift Solar is ramping up commercial production for "gigawatt-scale" production by 2030, showcasing the promising future of solar energy.
