An organic photovoltaic featuring graphene nanoribbons

A combination of graphene nanoribbons (GNRs) and carbon nanotubes (CNTs) was deployed as a potential candidate to replace the commonly used hole transport material poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) in a high performance organic photovoltaic. A power conversion efficiency (PCE) of 7.6% has been obtained using inkjet printing to fabricate the photovoltaic along with the presence of C-60-bis as an electron transporting material.
