Research
<p>To investigate the plasmonic effect in perovskite solar cells, the effect of depositing Au@SiO<sub>2</sub> nanoparticles on the top and the bottom of mesoporous TiO<sub>2</sub> layers was studied. First, Au@SiO<sub>2</sub> nanoparticles were synthesized. The particles were then deposited at the different interfaces of mesoporous TiO<sub>2</sub> layers. Although the two structures show approximately similar optical absorption, only cells with Au@SiO<sub>2</sub> nanoparticles deposited at the bottom of the mesoporous TiO<sub>2</sub> layers demonstrated an improved photocurrent performance compared to the reference cells. This structure shows a short-circuit current density (JSC) of 20.7 mA/cm<sup>2</sup> and open circuit voltage of 1081 mV. This enhancement may be attributed either to the interface surface engineering or plasmonic resonance of Au@SiO<sub>2</sub> nanoparticles depends to the NPs size and position. </p>
