Solar cell innovators in the US, such as Solx and Caelux, are teaming up to manufacture new tandem perovskite technology in Puerto Rico, aiming to offer a more economical alternative to traditional silicon cells with high-volume manufacturing potential. The Government of Puerto Rico is emphasizing the importance of solar energy as a solution to the island's weak infrastructure and dependence on imported fossil fuels. Solx's partnership with Caelux and Suniva seeks to revolutionize the American energy industry with a fully U.S.-based solar supply chain, highlighting the potential of U.S. manufacturers and technology leaders aligning to build a sustainable energy future and strengthen domestic energy security. This collaboration showcases the commitment to reshoring critical manufacturing capability and advancing solar technology in the face of challenges posed by current federal energy policies.
