Scientists led by China's Nanjing University discovered that a chemical commonly used for bleaching in the textile industry can also serve as a performance-boosting additive to mixed lead/tin perovskite thin films. Using this additive, they were ultimately able to fabricate a two perovskite tandem cell measuring 1.05cm² that achieved 24.2% efficiency.While perovskite-on-silicon tandem solar cells are currently the subject of plenty of commercial interest, the academic community is already looking further ahead. All perovskite tandem cells - where two different perovskite cells are stacked on ...Den vollständigen Artikel lesen ...
