- ... Modification of hole transporting layers has proved an effective approach to improve the photoelectric conversion efficiency of perovskite solar cells. In this work, we report a highly dispersed graphene composite prepared by skillfully using the synergistic π–π interaction between graphene sheets and functional carbon nanotubes (f-CNTs). The graphene:f-CNTs HTLs demonstrate excellent conductivity ...
