Perovskite solar cells (PSCs) is of particular interest because it can offer a number of advantages when compared to existing photovoltaic technologies. Searching for low cost, suitable alternatives to replace the present expensive components in PSCs is of vital importance for their further cost reduction and large-scale implementation. Carbon nanomaterials such as carbon nanotubes and graphene exhibit remarkable electrical, thermal, catalytic properties that enable exciting applications in PSCs. Herein, the utilization of carbon nanomaterials such as carbon nanotube and reduced graphene oxide as efficient economical hole transfer materials in PSCs is presented. Their suitable energy levels, high hole mobility and conductivity make it to be promising hole transfer materials instead of expensive spiro-MeOTAD in PSCs.
