Aqueous dye-sensitized solar cells (DSSCs) are emerging as a promising alternative to enhance both the lifetime and environmental friendliness of traditional DSSCs. Herein, cobalt-based, jellified (with xanthan gum) aqueous electrolyte, leading valuable efficiency exceeding 4% (VOC = 847 mV, JSC 6.73 mA cm?2, fill factor 74%), is reported. Design experiment used precisely significantly study, a...

During the light-harvesting process of dye-sensitized solar cells (DSSCs), the hole localized on the dye after the charge separation yields an oxidized dye, D(+). The fast regeneration of D(+) using the redox pair (typically the I(-)/I3(-) couple) is critical for the efficient DSSCs. However, the kinetic processes of dye regeneration remain uncertain, still promoting vigorous debates. Here, we ...

A silver nanoparticle-decorated N,S-co-doped TiO2 nanocomposite was successfully prepared and used as an efficient photoanode in high-performance dye-sensitized solar cells (DSSCs) with N719 dye. The DSSCs assembled with the N,S-TiO2@Ag-modified photoanode demonstrated an enhanced solar-to-electrical energy conversion efficiency of 8.22%, which was better than that of a DSSC photoanode composed...

2,6-Bis[1-(phenylimino)ethyl]pyridine (M0) and its derivatives containing methyl groups on their phenyl rings (M1o, M1p and M2) are employed as co-sensitizers in dye-sensitized solar cells (DSSCs). The prepared co-sensitizers could alleviate the aggregation of ruthenium dye N719 on the TiO2 film, enhance the spectral responses of the co-sensitized TiO2 film in the region from 400 to 750 nm, sup...

The replacement of oxide semiconducting TiO₂ nano particles with one dimensional TiO₂ nanotubes (TNTs) has been used for improving the electron transport in the dye-sensitized solar cells (DSSCs). Although use of one dimensional structure provides the enhanced photoelectrical performance, it tends to reduce the adsorption of dye on the TiO₂ surface due to decrease of surface area. To overcome t...

We synthesized platelet graphitic-nanofibres (GNFs) directly onto FTO glass and applied this forest of platelet GNFs as a highly porous structural counter-electrode in dye-sensitized solar cells (DSSCs). We investigated the electrochemical properties of counter-electrodes made from the highly porous structural GNFs and the photoconversion performance of the cells made with these electrodes.

Dye-sensitized solar cells (DSSCs) utilize high surface area metal oxide sintered particle networks to absorb molecular dyes and transport injected charge carriers. While this sintered particle architecture allows liquid electrolyte DSSCs to achieve efficiencies up to 11%, slow charge transport through the semiconductor network limits the amount of modification that can be made to the electroly...

Dye-sensitized solar cells (DSSCs) have aroused intense interest owing to their easy fabrication, low cost, simple preparation procedures and high energy conversion efficiency. Considering the fact that leakage and volatilization of liquid electrolytes hinder their practical applications in the case of DSSCs, polymer electrolytes with high ionic conductivity, excellent thermal and long-term sta...
