摘要
Perovskite solar cells (PSCs) commonly exhibit significant performance degradation due to ion migration through the top charge transport layer and ultimately metal electrode corrosion.Here,we demonstrate an interfacial management strategy using a boron chloride subphthalocyanine (Cl6SubPc)/fullerene electron-transport layer,which not only passivates the interfacial defects in the perovskite,but also suppresses halide diffusion as evidenced by multiple techniques,including visual element mapping by electron energy loss spectroscopy.As a result,we obtain inverted PSCs with an efficiency of 22.0% (21.3% certified),shelf life of 7000 h,T8o of 816 h under damp heat stress (compared to less than 20 h without Cl6SubPc),and initial performance retention of 98% after 2000 h at 80 ℃C in inert environment,90% after 2034 h of illumination and maximum power point tracking in ambient for encapsulated devices and 95% after 1272 h outdoor testing ISOS-O-1,Our strategy and results pave a new way to move PSCs forward to their potential commercialization solidly.
