AbstractDefective and mechanically weak interfaces substantially undermine both the efficiency and stability of perovskite solar cells (PSCs). Here we introduce a linear polymer, heparin sodium, as a multifunctional interface bridge layer in n–i–p PSCs. Unlike commonly employed small-molecule interface modification/passivation materials, heparin sodium features functional groups and ions including COO−, SO3− and Na+ distributed along the top and bottom sides of its backbone.
