We have developed a new ladder-type conjugated polymer PBDCPDTâFBT and a robust interconnecting layer (ICL) integrating a hole-collecting m-PEDOT:PSS layer with an electron-collecting ZnO layer. The inverted device using PBDCPDTâFBT exhibited a high power conversion efficiency (PCE) of 5.76% with a Voc of 0.81 V, a Jsc of 12.82 mA cmâ2, and a FF of 55.5%. The inverted tandem device incorporating the PBDCPDTâFBT and ICL achieves a Voc of 1.62 V leading to a PCE of 7.08%.
