Designing New Indene-Fullerene Derivatives as Electron-Transporting Materials for Flexible Perovskite Solar Cells

Year: 2021
Type: article
Abstract: High Resolution Image Download MS PowerPoint Slide The synthesis and characterization of a family of indene-C 60 adducts obtained via Diels–Alder cycloaddition [4 + 2] are reported. The new C 60 derivatives include indenes with a variety of functional groups. These adducts show lowest unoccupied molecular orbital energy levels to be at the right position to consider these compounds as electron-transporting materials for planar heterojunction perovskite solar cells. Selected derivatives were applied into inverted (p–i–n configuration) perovskite device architectures, fabricated on flexible polymer substrates, with large active areas (1 cm 2 ). The highest power conversion efficiency, reaching 13.61%, was obtained for the 6′-acetamido-1′,4′-dihydro-naphtho[2′,3′:1,2][5,6]fullerene-C 60 ( NHAc-ICMA ). Spectroscopic characterization was applied to visualize possible passivation effects of the perovskite’s surface induced by these adducts.
