Organic solar cells are one of the alternative energy sources. The only barrier to commercialization of this technology is its low efficiency values. In this study, the efficiency of inverted organic solar cells was increased by utilizing the plasmonic effects of Ag nanoparticles (np). The device configuration is ITO/ZnO/poly(3-hexylthiophene-2,5-diyl) (P3HT):(6,6)-phenyl C61 butyric acid methyl ester (PCBM)/MoO3/Ag. Ag np’s were synthesized by polyol method and characterized by X-Ray diffractometry (XRD), Uv-Vis spectrophotometer and field emission scanning electron microscopy (FESEM). Afterwards, Ag was added to P3HT:PCBM at the ratios of 0.125-0.25-0.5% by mass. While the efficiency value was 3.21% in the reference cell, it reached 3.43% with an increase of approximately 7% in the 0.25% Ag added device.
