We use free-standing TiO2 nanotube membranes that are transferred onto FTO slides in front-side illuminated dye-sensitized solar cells (DSSCs). We investigate the key parameters for solar cell arrangement of self-ordered anodic TiO2 nanotube layers on the FTO substrate, namely the influence of the annealing procedure on the DSSC light conversion efficiency. The results show that using an optima...

We report a new water soluble and stable thiolate/disulfide redox couple (T(-)/DS) and its use with a new zwitterionic and thiocyanate-free dye (T169) in a 100% aqueous electrolyte system. A DSSC incorporating T169 and the T(-)/DS showed the highest photocurrents (Jsc = 13.30 mA cm(-2)) and IPCE% (84%) values reported to date. In addition, a 2000 h long-term stability measurement was performed,...

High-density vertically aligned ZnO nanotube arrays were fabricated on FTO substrates by a simple and facile chemical etching process from electrodeposited ZnO nanorods. The nanotube formation was rationalized in terms of selective dissolution of the (001) polar face. The morphology of the nanotubes can be readily controlled by electrodeposition parameters for the nanorod precursor. By employin...

in this investigation, ag@tio2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial tio2 nanoparticles (known as p25 tio2) via photodeposition technique as clean and simple photochemical route. the synthesized ag@tio2 nanocomposite was utilized in the fabrication of dye-sensitized solar cell (dssc) chiefly because, compared to pure tio2, the electron affinity of ag@ti...

Y1.86Eu0.14WO6 phosphors were prepared using a solid-state reaction method. Their optical properties were analysed, and they was mixed with TiO2, sintered, and used as a photoelectrode (PE) in dye-sensitized solar cells (DSSCs). The as-prepared photoelectrode was characterized by photoluminescence spectroscopy, diffuse reflectance, electrochemical impedance spectroscopy (EIS) and X-ray diffract...

To reduce costs, a low-cost thin-film solar cell technique known as the Dye Sensitized Solar Cell (DSSC)/Gratzel emerged. DSSC is an easy to manufacture photovoltaic but lacks its stability and higher conversion efficiency factors. In this paper, overcome these challenges keep cost factor on trial, photogalvanic was also studied using H-shaped glass tube. Both cells were dyes Erythrosin B, Tart...

We have designed and synthesized a new thiocyanate-free sensitizer coded as SPS-01 and used it as the sensitizer in a TiO(2) based nanocrystalline dye-sensitized solar cell (DSSC). SPS-01 exhibits strong visible absorption properties with maximum peak around at 532 nm. The overall power conversion efficiency (PCE) of a DSSC sensitized with SPS-01 (7.96%) is higher than that of N719 (7.30%) unde...

A novel titanium dioxide paste based on Pechini sol-gel method and nanocrystalline TiO2 powder has been successfully developed and tested. The paste enables the formation of sponge like structure of the TiO2 layer i.e. highly porous and at the same time well connected TiO2 network. The layers have been used to assemble dye sensitized solar cells (DSSC) with two ruthenium complex based dyes, N71...

Dye-Sensitized Solar Cell (DSSC) is a solar cell that uses dyes to convert sunlight into electricity, which has wide absorption spectrum, inexpensive and environmentally friendly. Visible light sensitive are used in types generate electricity. Natural commonly DSSC chlorophyll derived from plants. Chlorophyll source of electrons will be excited when exposed light, resulting an electric current ...
