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.

California may order 6 GW early to secure expiring renewables credits
A CPUC judge in California has proposed ordering an additional 6 GW of electric capacity between 2029 and 2032 to take advantage of expiring federal tax credits for renewable energy projects, as part of the state's goal to procure over 40 GW of capacity by 2032. The focus is on utility-scale solar, battery storage, wind capacity, and non-lithium-ion long-duration storage to achieve 100% emissions-free electricity by 2045. This initiative is driven by the expected increase in electricity demand due to data center growth, electric vehicle charging, and building electrification. Stakeholder comments on the 6 GW procurement proposal will be collected until October 22, 2025.
