Preparation of efficient inverted tin-based perovskite solar cells via the bidentate coordination effect of 8-hydroxyquinoline

The N and O atoms in the bidentate ligand 8-hydroxyquinoline (8-HQ) can simultaneously coordinate with Sn 2+ , which greatly inhibits the oxidation of Sn 2+ . The formation of complexes improves the quality of FASnI 3 films and reduces defect states, resulting in improvements in the efficiency and s...

Summary:The N and O atoms in the bidentate ligand 8-hydroxyquinoline (8-HQ) can simultaneously coordinate with Sn 2+ , which greatly inhibits the oxidation of Sn 2+ . The formation of complexes improves the quality of FASnI 3 films and reduces defect states, resulting in improvements in the efficiency and stability of FASnI 3 -based perovskite solar cells.
