Abstract

In this work, P3HT:PCBM based organic solar cells (OSCs) were fabricated. We investigated the protection of PEDOT:PSS from active layer using the solution processed molybdenum oxide nanoparticles layer (MoO₃ NPs, ≤100 nm). The device structure was ITO/ZnO/P3HT: PCBM/MoO₃/PEDOT:PSS/Ag. A thin film MoO₃ NPs was spin-coated and it acts as a hole transporting layer between the active layer and PEDOT:PSS. The MoO₃ NPs based device showed an improved short circuit current compared without MoO₃ NP layer. The pristine OSCs showed short circuit current density (J_sc) of 11.56 mA/cm² and PCE of 3.70% under AM 1.5G (100 mW/cm²). MoO₃ NPs based device showed an increased PCE of 4.11% with J_sc of 12.74 mA/cm². MoO₃ NPs also decreased the charge recombination and resistance of the OSCs. [Figure not available: see fulltext.]
