Development of Materials and Interface Engineering Technologies for Dye-Sensitized Solar Cells
During the past decade, refinements in the chemical components of solar cells, improvements in cell physics, and device engineering have led to remarkable enhancement of dye-sensitized solar cell performance. These enhancements canpotentially provide low-cost, large-area, flexible, and high efficiency solar cells for all Partner countries. The goal of this project is to develop materials and ...

Performances of natural dye–sensitised solar cells - a brief review
Dye–sensitised solar cells (DSCs), also called as photoelectrochemical cells, have the potential of commercial viability and are the most promising photovoltaic devices among the new generation of renewable energy systems. The dye used is responsible for the light harvesting efficiency and electron injection efficiency of the DSC. Vast amount of work has been done on the performance of DSCs with ...

Highly crystalline hydrothermal ZnO nanowires as photoanodes in DSCs
Vertically aligned ZnO nanowires (NWs) were prepared inside an autoclave by a hydrothermal procedure at temperatures above 100°C (HP). The effects of synthesis temperature and time on the morphology of ZnO NWs were carefully studied. The performance of HP ZnO NWs was compared with that of ZnO NWs grown by a conventional ambient pressure hydrothermal method at temperatures below 100°C (LP) ...

Iron Oxide and Iron Sulfide Films Prepared for Dye-Sensitized Solar Cells
Abstract: In this paper, the prospects of iron oxide films and their sulfidation for dye-sensitized solar cells (DSSC) are reviewed. Iron oxide thin films were prepared by hollow cathode plasma jet (HCPJ) sputtering, with an admixture of oxygen in the argon working gas and with an iron nozzle as the sputtering target. The discharge was powered by a constant current source in continuous mode and ...

Gold nanoparticles functionalised with Ru–dicarboxybipyridine–trimercaptotriazine: SERS effect and application in plasmonic dye solar cells
A dicarboxybipyridine–trimercaptotriazine ruthenium complex, primarily designed for dye–sensitised solar cells (DSSC), has been successfully employed in the generation of electrostatically stabilised gold colloids, because of its high negative charge and capability of binding to gold nanoparticles via the sulphur groups. Strong SERS enhancements have been obtained for the isolated gold ...

Prompting electron transport in mesoporous semiconductor electrode by simple film compression
Tuning materials packing in the photoanode films through a simple cold isostatic pressing (CIP) post-treatment allows highly efficient charge transport and a dramatically retarded recombination that are witnessed by electrochemical impedance spectroscopy (EIS) studies. The pressing post-treatment produces densely packed TiO 2 nanoparticle film with fewer relatively large vacancies and better ...

Effect of seed particle size and ammonia concentration on the growth of ZnO nanowire arrays and their photoconversion efficiency
ZnO nanowire arrays were synthesised for dye-sensitised solar cell applications using the chemical bath deposition technique. To study the effect of the particle size in the seed layer on the growth and resultant photoconversion efficiency, we prepared various seeded FTO substrates by repeating the seed layer sol-gel coating process. It was found that changing the number of coating process ...

Tungsten trioxide nanostructured electrodes for organic dye sensitised solar cells
Tungsten trioxide (WO 3 ) nanospheres with diameter ranging from 10 nm to 500 nm were synthesised by a facile thermal oxidation process. By resistively heating metallic tungsten in oxygen atmosphere, WO 3 nanoparticles were produced in high yield. Optical, compositional, morphological and structural studies were performed by UV-VIS-NIR spectrophotometry, X-ray photoelectron spectroscopy ...

Water vapour permeation measurement for PV Solar Cell packaging
With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries. As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies. At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter technology ...
