In this work, Ag@SiO2 core–shell nanoparticles were prepared using the laser ablation technique and employed these nanoparticles in plasmonic-sensitized solar cells (DSSC). Current–voltage (I–V) characteristic curves of DSSCs were performed both in the dark and under 100 mW/cm2 and obtained experimental results compared to each other at room temperature. Ag@SiO2 core–shell NPs were prepared using different laser energies (50 mJ, 100 mJ, 150 mJ) by pulsed laser ablation in an aqueous silica solution. The results highly showed the effect of the used laser energy on the structural properties of the prepared nanoparticles, which in turn affect the other properties. The XRD for Ag@SiO2 shows that the crystallinity enhanced, and the crystallite size increased with increasing the laser energy (18.8 nm for 50 mJ, 24.5 nm for 100 mJ, 34.9 nm for 150 mJ). The transmission electron microscopy shows an increasing average diameter for both NPs types with the laser energy. The UV–visible absorbance shows significant plasmonic resonance bands around 400 nm for the Ag@SiO2, with a small red shift increasing the laser energy. Incorporating metal NPs into solar cell layers enhances their efficiency by increasing the active layer's absorption, especially at the plasmonic frequency. The effect of the different NPs was examined and compared with the bare-solar cell without nanoparticles. The DSSC solar cell composed of Ag@SiO2 NPs significantly enhances their characteristics. The results revealed that Ag@SiO2 could be employed as selective scattering factors, promising efficient DSSCs.
