A study was conducted to demonstrate graphenized carbon nanofiber as a novel light-trapping and conductive material to achieve an efficiency breakthrough in silicon solar cells. The study presented a new pathway to solve the bottleneck issues and provide a significant performance improvement on silicon-based solar cells with the latest efficiencies. The concept of the novel nanomaterial and solar cell design was based on a novel synthesis process in which graphitized carbon fibers were used as the synthesis precursor. It was demonstrated that an innovative 1D graphenized carbon nanofiber (GCNF) could be achieved through longitudinal wall cutting by the wet chemical method.
