Sol-electrophoretic deposition of TiO2 nanoparticle/nanorod array for photoanode of dye-sensitized solar cell

Recent progress in one dimensional TiO2nanomaterials as photoanodes in dye-sensitized solar cells

“…Several NR/NP bilayered photoanode structures were fabricated later. 151,155,156,[166][167][168][169][170] These bilayer structures provided enhanced light scattering as well as increased surface area, which is nally reected in their increased efficiencies (Fig. 12).…”

“…Here sol-gel derived NP layer was coated with hydrothermally prepared NRs and this DSSC assembly exhibited an efficiency of 7.1%. Several NR/NP bilayered photoanode structures were fabricated later 151,155,156,[166][167][168][169][170] . These bilayer structures provided enhanced light scattering as well as increased surface area, which is finally reflected in their increased efficiencies (Fig.…”

Fabrication of cellulose paper-based counter electrodes for flexible dye-sensitized solar cells

“…[5][6][7] FDSSCs are an exciting innovation mainly due to tremendous features over the basic DSSC and Si-based modules, including reduced manufacturing cost, ease of processing, functionality, reasonable electrical efficiency, and other aspects. [8][9][10][11][12][13][14] In a typical DSSC, along with the working electrode (WE) and a redox electrolyte, the counter electrode (CE) also plays a crucial role in determining the overall cell power conversion efficiency. [15][16][17][18] The DSSC CE performs two essential roles: it supports the electrolyte reduction, which provides uninterrupted electricity generation, and acts as a means of transferring electrons from the outer circuit back to the electrolyte.…”

Impact of TiO2 Nanostructures on Dye-Sensitized Solar Cells Performance

“…Thus, the photoanodes combining hybrid nanostructures of 1D and 3D nanostructures have attracted attention due to the streamlined electron transport, efficiency of the charge collection, and relatively low recombination rate [ 33 , 34 , 35 ]. However, the main problem in DSSCs based on nanowire/nanorod-based is the inadequate surface area for dye loading and hence insufficient light scattering ability [ 36 , 37 ]. The problem could be solved by the addition of the TiO 2 electrospun nanofibers/nanoparticles combination, which improves charge transport as well as light scattering with no loss in dye loading.…”
