چکیده
Different nanostructured semiconducting ZnO photoanodes were prepared by Hydrothermal (HT), Co-precipitation (CoP) and Chemical Bath Deposition (CBD) methods for their use in the Dye Sensitized Solar Cells (DSSCs) present study. Additionally, different nanocomposites synthesized mixing Carbon Nanotubes (CNTs), Graphene Oxide (GO) combination with nanostructures. Scanning electron microscopy (SEM) revealed various morphologies of nanostructures such as nanoflowers, nanorods, rhombohedral, cubic, cauliflower-like nanorods hexagonal symmetry. Energy Dispersive X-ray (EDX) spectra confirmed purity samples. Diffraction (XRD) demonstrated wurtzite phase a minor presence CNTs graphene. The UV-Visible, transmittance diffuse reflectance that through CBD method exhibits highest 70–71% UV-Vis range reduced % R. Optical band gaps samples determined help Tauc plots. Comparison J-V characteristics showed via HT conversion efficiency 1.45%. among pristine ZnO/CNTs possesses energy 1.23% enhanced JSC 4.49 mA/cm2.

Recent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells
Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes have shown significant properties such...
متن کاملApplication of azo dye as sensitizer in dye-sensitized solar cells
An azo dye used as photosensitizers in Dye-sensitized solar cells DSSCs. Azo dyes economically superior to organometallic dyes because they are color variation and cheap. The spectrophotometric evaluation of an azo dye in solution and on a TiO2 substrate show that the dye form J-aggregation on the nanostructured TiO2 substrate. Oxidation potential measurements for used azo dyes ensured an energ...

We have synthesized a highly efficient organic dye for a dye-sensitized solar cell; the overall solar-to-energy conversion efficiency was 9.1% at AM 1.5 illumination (100 mW cm(-2)): short-circuit current density (J(sc)) = 18.1 mA cm(-2), open circuit photovoltage (V(oc)) = 743 mV and fill factor (ff) = 0.675.
متن کاملHighly efficient photocathodes for dye-sensitized tandem solar cells.
Thin-film dye-sensitized solar cells (DSCs) based on mesoporous semiconductor electrodes are low-cost alternatives to conventional silicon devices. High-efficiency DSCs typically operate as photoanodes (n-DSCs), where photocurrents result from dye-sensitized electron injection into n-type semiconductors. Dye-sensitized photocathodes (p-DSCs) operate in an inverse mode, where dye-excitation is f...
متن کاملHierarchically structured nanotubes for highly efficient dye-sensitized solar cells.
Hierarchical TiO2 nanotube arrays grown on Ti foil are yielded by subjecting electrochemically anodized, vertically oriented TiO2 nanotube arrays to hydrothermal processing. The resulting DSSCs exhibit a significantly enhanced power conversion efficiency of 7.24%, which is a direct consequence of the synergy of higher dye loading, superior light-scattering ability, and fast electron transport.
