A new n‐type polymer, PF3N‐2TNDI, with high electron mobility , is developed as efficient cathode interfacial material and interconnecting layer (ICL) for constructing high‐performance tandem organic solar cells. Tandem cells employing the ICL with structure of PF3N‐2TNDI/Ag/PEDOT:PSS achieve a high power conversion efficiency (PCE) of 11.35%. Moreover, flexible tandem cells with PCE over 10% are also demonstrated.
