One of the major and unique components of dye-sensitized solar cells (DSSC) is the iodide/triiodide redox couple. Periodic density-functional calculations have been carried out to study the interactions among three different components of the DSSC, i.e. the redox shuttle, the TiO(2) semiconductor surface, and nitrogen containing additives, with a focus on the implications for the performance of...

A novel dye-sensitized solar cell (DSSC) structure using vertically aligned single-walled carbon nanotubes (VASWCNTs) as the counter electrode has been developed. In this design, the VASWCNTs serve as a stable high surface area and highly active electrocatalytic counter-electrode that could be a promising alternative to the conventional Pt analogue. Utilizing a scalable dry transfer approach to...

Abstract Ensuring high power conversion efficiency, partially or completely replacing Pt electrodes with inexpensive materials is one of the important development directions dye-sensitized solar cells (DSSCs). In this work, we have developed a three-component (MWCNTs, carbon black and graphite) (tri-carbon) electrode material for DSSC devices combined advantages electron transfer kinetics MWCNT...

A simple and low-cost fabrication method of dye-sensitized solar cells (DSSCs) was developed to improve the structure performance photoanode with pressed layer compact TiO2 thin film using spin coating, screen printing, mechanical compression. In this study, four different layers were adopted fabricate photoanodes: a mesoporous nanoparticles (NPs) layer, NPs on film, film. The deposited fluorin...

in this study, we investigated the effect of using large tio2 nanoparticles in the matrix of small nanoparticles to improve the performance of dye-sensitized solar cells (dsscs), as light scatter to increase the light harvesting. the mixed powder was deposited by electrophoretic deposition (epd) on fto (f-sno2 coated glass). it is shown that adding small quantity of larger nanoparticles can enh...

In this article, silver nanowires (AgNWs) were prepared and introduced into the double-layer photoanode of dye-sensitized solar cells (DSSCs). Silver with a diameter about 50–60 nm length 1–2 mm by polyol method. The power conversion efficiency DSSC made AgNWs@TiO2 AgNPs@TiO2 composite materials is 6.38%. Compared unmodified DSSC, combined AgNWs AgNPs increased 58.7%. This was mainly due to loc...

Intermolecular interactions in cyclometalated Ru complex dye (FT89) dimers, carbazole organic dye (MK-45 and MK-111) dimers, FT89-MK-45 complexes, and FT89-MK-111 complexes were investigated using density functional theory (DFT) and time-dependent DFT (TD-DFT) to elucidate the improvement mechanism of dye-sensitized solar cell (DSSC) performance due to cosensitization with FT89 and MK dyes. All...

Aligned ZnO nanowires with different lengths (1 to approximately 4 μm) have been deposited on indium titanium oxide-coated glass substrates by using the solution phase deposition method for application as a work electrode in dye-sensitized solar cells (DSSC). From the results, the increases in length of zinc oxide (ZnO) nanowires can increase adsorption of the N3 dye through ZnO nanowires to im...
