“…The Manjifera Indica, Manihot Esculenta and Hibiscus Sabdariffa leaves were individually procured directly from their trees in Agbor, Delta State; then, washed and sun dried. These leaves were air dried in a shade to avoid the bleaching of the pigments (Eli, et al, 2016). Each of the Mangifera Indica, Manihot Esculenta and Hibiscus Sabdariffa leaves samples was weighed using an electronic weighing balance; 10 g each.…”

A threat to the energy production in the world is emerging mainly because of the shortage of energy resources and world industrialization. Although the cost factor is also a problem here, the future of solar energy is now growing and its conversion efficiency is also increasing. An important realization that can be made is that a dye-sensitized solar cell is a means of refining solar energy conversion technology, in which the use of wide bandgap semiconductors is based on photocurrent. Among the elements of the dye –sensitized solar cell, the dye as a sensitizer determines the performance of the cell. Common natural dyes are obtained from leaves, flower petals, and roots for instance. Considering the aspect of simplicity and cost of natural dyes, less complex extraction process than synthetic dyes and being friendly to the environment, researchers are striving to find ways of replacing the synthetic dyes with natural dyes. Here, TiO2 was prepared with the Sol-gel spin coating method with titanium tetraisopropoxide, isopropanol, acetic acid, and deionized water as precursors. The results showed that there was changes in the optical properties like transmittance, reflectance, and bandgape energy when the dye leave extract of Mangifera Indica, Manihot Esculenta, and Hibiscus Sabdariffa was examined. Morphological and compositional properties of the nanostructured TiO2 are also ascertained.

“…8, the open-circuit voltage (Voc) of plasmonenhanced DSSCs and TiO 2 -only DSSC are almost the same, while the short-circuit current density (Jsc) significantly increased by introducing Ag@SiO 2 NPs. The improvement of Jsc in the plasmon enhanced DSSCs was mainly caused by the increase of photocurrent due to the enhanced light absorption of dye with the help of localized surface plasmons (LSPs) [23][24][25][29][30][31].…”

Abstract:We present an investigation on introducing core-shell Ag@SiO 2 nanoparticles (NPs) into dye-sensitized solar cells. Ag@SiO 2 present the chemical stability to iodide/triiodide electrolyte, and help to localize most of dye molecules around plasmonic silver nanoparticles (AgNPs), hence increasing the optical absorption consequently the overall conversion efficiency of the device. Deployment of the silver-modified assembly as a photo anode in dye-sensitized solar cells leads to solar-toelectrical energy conversion with an overall efficiency of 0.0088% for Ag-TiO 2 photo anode and 0.0176% for Ag@SiO 2 -TiO 2 photo anode. This represents a 100.7% improvement over the performance of otherwise identical solar cell lacking corrosionprotected silver nanoparticles. The improvement is manifested chiefly as an increase in photocurrent density due to enhanced light harvesting by the AgNPs. The results revealed that, the performance of DSSCs could be well improved through enhancing the light absorption by local surface plasmon (LSP) effect from Ag@SiO 2 NPs by electronically and chemically protecting the metal from recombination and corrosion. The mechanism of getting the best utilization efficiency of LSP enhanced optical field is also investigated.

Abstract:The enhancement in efficiency of dye sensitized solar cells decorated with size-controlled silver nanoparticles based on anthocyanins as light harvesting pigment through successive ionic layer adsorption and reaction (SILAR) was demonstrated. Studies indicate that, the short-circuit current density (J SC ) and open-circuit voltage (V OC ), of DSSCs containing AgNPs were significantly improved. The photovoltaic (PV) performance decreased with increasing size of AgNPs from one SILAR cycle to two SILAR cycles, the best performance was achieved using the anode prepared with one SILAR cycle. An enhancement of 35.8 % was achieved when the thickness was around 16 nm (one SILAR) over the bare FTO device. When the size of AgNPs was around 32 nm (two SILAR), an enhancement of 10.4% was recorded over the reference device. This selective enhancement in efficiency in the Ag plasmonic absorption regions is indicative of the fact that the incorporation of metal nanoparticles is beneficial for enhanced absorption and charge separation.
