• We have developed a new ladder-type conjugated polymer PBDCPDT-FBT and a robust interconnecting layer (ICL) integrating a hole-collecting m-PEDOT:PSS layer with an electron-collecting ZnO layer. The inverted device using PBDCPDT-FBT exhibited a high power conversion efficiency (PCE) of 5.76% with a V oc of 0.81 V, a J sc of 12.82 mA cm −2 , and a FF of 55.5%. The inverted tandem device incorporating the PBDCPDT-FBT and ICL achieves a V oc of 1.62 V leading to a PCE of 7.08%. A new ladder-type polymer PBDCPDT-FBT and a robust interconnecting layer have led to a tandem device with a high PCE of 7.08%.
