摘要：

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%.
