Synthesis of vertically grown N,N′-dioctyl-3,4,9,10-perylenedicarboximide nanostructure for photovoltaic application

We report here the formation of vertical N,N′-dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) nanostructure with simple chemical treatment over thermally evaporated thin film of PTCDI-C8. Here, we have used PTCDI-C8 nanostructures as an electron accepting material and a conjugated polymer as an electron donor material in the solar cell device. The study shows that the utilization of nanostructure over bilayer architecture gives better performance. The higher donor/acceptor effective interface and its effect on the device performance are realized with the nanostructured PTCDI-C8 layer.
