摘要：

As a thin cathode buffer layer (CBL) tris-(8-hydroxyquinoline), aluminum (Alq(3)) is successfully introduced into the planar p-i-n perovskite solar cells (PSC) between the PCBM layer and cathode with a device structure of ITO/PEDOT: PSS/CH3NH3PbI3(Cl)/PCBM/Alq(3)/Ag. Due to the as-introduced thin Alq(3) CBL, a high performance planar PSC has been achieved with a fill factor (FF) of 72% and maximum power conversion efficiency (PCE) of 14.22%. The PCE value is approximately 29% higher than that of the reference device without Alq(3) CBL. Concerning the results of AC impedance spectra and transient photocurrent measurements, such a remarkable improvement of PCE is mainly attributed to the Alq(3)-caused better charge-extraction at the cathode, which is induced by reducing charge accumulation between PCBM and Ag.
