Work‐Function‐Tunable Chlorinated Graphene Oxide as an Anode Interface Layer in High‐Efficiency Polymer Solar Cells

Chlorinated graphene oxides (Cl-GO), which have good optical transmission, high work functions, and excellent hole-extraction abilities, are demonstrated as anode interface materials. High-efficiency polymer solar cells based on different materials are fabricated. The improvement of the power conversion efficiency is much higher when the highest occupied molecular orbital (HOMO) of the polymers is closely aligned with the work function of the Cl-GO.
