photovoltaic solar cell in the presence of Iron (III) oxide nanoparticles (Fe2O3 NPs). This
latter is deposited at the hole's interface collecting the layer of buffer [poly (styrenesulfonate):
poly (o-toluidine) and poly (3, 4ethylenedioxythiophene)(PEDOT: PSS)] and (POT) Zinc
Oxide Nanoparticle (ZnONPs) active layer. This additive at the interface was noticed to
considerably elevate the performances of the solar cell. These devices' photo-physical …
