Quantifying Mobile Ions in a Perovskite-based Tandem Solar Cell
Perovskite–silicon tandem solar cells are a promising pathway to surpass the efficiency of traditional silicon devices. This research focuses on measuring mobile ion concentration in perovskite, silicon, and perovskite–silicon tandem cells to better understand how it affects device performance and stability. Unlike silicon, which has strong covalent bonds, perovskites contain weaker ionic bonds that allow their ions to more easily move within the material. Mobile ions in perovskites can influence charge transport and impact long-term stability. By comparing these configurations, this work aims to explain how ion behavior shapes the efficiency of tandems and the development of improved solar technologies.
