This study prepared Au nanoparticles (NPs) with different sizes and two kinds of core-shell NPs of Au@SiO2 and SiO2@Au. Absorption spectra and surface-enhanced Raman scattering showed good surface plasmon enhancement effect of these NPs. Incorporation of Au NPs with different sizes into different positions posed different effects on the performance of ZnO-based inverted PTB7:PC71BM polymer solar cells. Rather than into the active layer, Au NPs were added to ZnO electron transport layer (ETL) and resulted in better efficiency enhancement as a result of localized surface plasmon resonance effect. Addition of 40 nm Au NPs in ZnO ETL resulted in 10% efficiency enhancement from 3.20 to 3.52%. Addition of Au@SiO2 and SiO2@Au core-shell NPs to ZnO ETL led to a more remarkable efficiency enhancement, reaching 3.99 and 4.20%, respectively.
