NREL & CubicPV Push Perovskite Minimodule Performance to New Heights - CleanTechnica

A collaboration between the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) and Boston-based CubicPV has achieved a new record in perovskite minimodule efficiency, reaching a certified 24.0%. This marks the first time a U.S. team has set a record in this category. The minimodule, composed of multiple interconnected cells, was fabricated through combined efforts at both organizations, leveraging their complementary expertise. NREL focuses on advancing manufacturing, durability, and efficiency of perovskite-enabled tandem solar cells, while CubicPV specializes in tandem devices that layer perovskites on silicon to capture more photons and reduce energy costs. Perovskite solar technology is notable for its low-temperature, ink-based or vacuum coating production processes using earth-abundant materials, offering a promising alternative to traditional silicon solar cells. While small-scale perovskite cells have demonstrated high efficiency, scaling up to larger-area devices with improved durability remains a key challenge for commercial viability
