Preparation and properties of nanostructured TiO2 electrode by a polymer organic-medium screen-printing technique

A New Type of Dye‐Sensitized Solar Cell with a Multilayered Photoanode Prepared by a Film‐Transfer Technique

“…After cooling to 80 ° C, the obtained fi lms were soaked in an acetonitrile/4-tertbutyl alcohol (1:1, v/v) solution containing 0.5 m M dye (N719 or AP) for 20-22 h. To prepare the layer for transfer, the pastes of P25 (Degussa) and ST41 (Degussa), prepared according to the procedure developed by our group, were coated onto the smooth surface of a ceramic tile with an area slightly larger than the bottom layer, followed by sintering at 500 ° C for 30 min. [ 30 ] The multilayered photoanode was fabricated using the bottom layer sensitized with dye1 (N719 or AP) to transfer the porous P25/ST41 scattering layer under friction. [ 31 ] After compression with pressure of about 2 × 10 3 kgf cm …”

Optimization of nanostructured titania photoanodes for dye-sensitized solar cells: Study and experimentation of TiCl4 treatment

“…The first porous layer is responsible for the increase in the amount of the dye adsorbed and makes a simple electrolyte diffusion. The scattering of light, due to the second layer, increases the path length of photons inside the cell and the probability to interact with a dye molecule [6]. The photon-trapping effect can be so induced by the use of a combination of a transparent nanocrystalline TiO 2 film with a microcrystalline light-scattering layer [7,8], in conjunction with the anti-reflecting film (ARF) [9] and other techniques [10].…”

Layer-by-layer deposition of open-pore mesoporous TiO2-Nafion® film electrodes

“…New alternative strategies for the deposition of ordered TiO 2 films include nanotube growth [6] and sol-gel dip-coating [7], but the more commonly employed direct deposition of nanoparticulate material is usually sufficient for most thin film applications. Porous membranes of TiO 2 have been formed by doctor-blading [8], printing [9], and by layer-by-layer deposition [10] of an alternating sequence of a negatively charged binder and the positively charged nanoparticulate TiO 2 .…”
