Swift Solar

Swift Solar is a U.S.-based solar technology company founded in 2017. It specializes in designing and manufacturing high-performance perovskite tandem solar panels, which are more efficient and cost-effective than traditional silicon-based panels. The company emerged from leading research institutions, including Stanford University, MIT, and the U.S. Department of Energy’s National Renewable Energy Laboratory. The company develops lightweight, flexible solar panels that utilize a tandem architecture to capture a broader spectrum of sunlight, enhancing efficiency. Swift Solar's technology is particularly suited for applications requiring high performance and low weight, such as unmanned aerial vehicles and mobile solar solutions. The company is scaling its manufacturing capabilities and plans to establish its first factory in the U.S. to produce these innovative solar panels at a commercial scale. Swift Solar has raised $44 million in funding and has received several accolades, including the R&D 100 Award and recognition as one of TIME’s Top GreenTech Companies in America.
