The　plasmonic　effects　of　silver　(Ag)　nano-particles　(NPs)　with　various　morphologies　(sphere,　rod,　and　prism)　embedded　into　the　platinum　(Pt)　counter　electrodes　(CEs)　of　dye-sensitized　solar　cells　(DSCs)　were　systematically　investigated.　It　was　shown　that　the　power　conversion　efficiencies　(PCEs)　of　the　incorporated　devices　are　notably　improved　from　7.60%,　for　the　reference　device　without　Ag　NPs,　to　8.10,　8.68,　and　8.55%　with　Ag　nanospheres,　nanorods,　and　nanoprism　devices,　respectively.　Moreover,　the　photo　current　and　fill　factor　enhancement　is　attributed　to　the　better　optical　and　electrical　properties　of　the　integrated　devices.　Among　all　of　the　NP　morphologies　studied,　Ag　nanorods　offer　the　best　improvement　to　the　device　efficiency,　as　they　have　longitudinal　localized　surface　plasmon　resonance　(L-LSPR)　and　strong　scattering　effects　correlate　within　the　morphology.
