Innovative Coating Boosts Efficiency and Lowers Costs of Solar Cells
Sydney, Australia (SPX) Aug 02, 2024 - A coating of solar cells with unique organic molecules could pave the way for more efficient and affordable solar panels. As reported in the journal Angewandte Chemie, this coating enhances the effi
Monolithic tandem cells are created by layering these semiconductors on a support, typically using silicon wafers produced by the zone melting process with a polished or nanostructured surface. Cheaper silicon wafers produced by the Czochralski process feature micrometer-scale pyramidal structural elements that enhance light capture due to their lower reflectivity compared to smooth surfaces. This surface modification enables perovskite/silicon tandem solar cells, based on common textured Czochralski silicon wafers, to achieve nearly 31% efficiency and maintain long-term stability.
