The goal of this work was to optimize the combination natural dyes producing panchromatic absorption matched AM1.5 solar spectrum for use in dye sensitized cells (DSSCs). Six classes (Anthocyanins, Betalins, Chlorophyll, Xanthonoids, Curcuminoids and Phycobilins) were explored. UV-Vis data radial basis function interpolation used model absorbance 2568 combinations, three objective functions det...

Graphene has been envisaged as a highly promising material for various field emission devices, supercapacitors, photocatalysts, sensors, electroanalytical systems, fuel cells and photovoltaics. The main goal of our work is to develop new Pt and transparent conductive oxide (TCO) free graphene based counter electrodes (CEs) for dye sensitized solar cells (DSSCs). We have prepared new composites ...

In this paper, Reduced Graphene Oxide (rGO)/ZnFe2O4 (rZnF) nanocomposite is synthesized by a simple hydrothermal method and employed as counter electrode (CE) material for tri-iodide redox reactions in Dye sensitized solar cells (DSSC) to replace the traditional high cost platinum (Pt) CE. X-ray diffraction analysis High resolution Transmission electron microscopy, clearly indicated formation o...

Localized surface plasmon resonance (LSPR) has been applied in photovoltaic devices to improve their photoelectric conversion efficiency. In this study, the mechanism of LSPR dye-sensitized solar cells (DSSCs) was determined. Specifically, silver nanoparticles were formed by evaporating electro-beam equipment and then annealing it a tube furnace. The sizes varied with changes thicknesses during...

Surface modification plays a crucial role in improving the efficiency of dye-sensitized solar cells (DSSCs), but the reported surface treatments are in general superior to the untreated TiO(2) but inferior to the typical TiCl(4)-treated TiO(2) in terms of solar cell performance. This work demonstrates a two-step treatment of the nanoporous titania surface with strontium acetate [Sr(OAc)(2)] and...

TiO2 mesoporous nanoparticles (NPs) doped with yttrium (Y) ions are fabricated via an environmentally friendly and facile solvothermal method to serve as a photoanode for dye sensitized solar cells (DSSCs). X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy and N2 adsorption-desorption tests are used to characterize the influence of yttrium dopant on the prope...

Environmental conditions influence the development of solar cell technologies; variables such as irradiation, wind speed, and ambient temperature operating cells, which affect their electrical performance; however, this effect may differ according to technology. In case Dye-Sensitized Solar Cells (DSSCs), it is necessary generate more studies evaluate behavior in different types climates under ...

A tetra-arylporphyrin dye was functionalized with three different anchoring groups used to attach molecules to metal oxide surfaces. The physical, photophysical and electrochemical properties of the derivatized porphyrins were studied, and the dyes were then linked to mesoporous TiO2. The anchoring groups were β-vinyl groups bearing either a carboxylate, a phosphonate or a siloxy moiety. The si...

A chemically sintered and binder-free paste of TiO2 nanoparticles (NPs) was prepared using a binary-liquid mixture 1-octanol CCl4. The 1:1 (v/v) complex CCl4 easily interacted with the NPs induced formation highly viscous paste. as-prepared (<bold>P</bold>BL)-based film exhibited complete removal residuals subsequent low-temperature sintering (~150°C) UV-O3 treatment. This facilitat...
