A photoanode with Ga-doped ZnO nanorods has been prepared on F-doped SnO2 (FTO) coated glass substrate and its application in dye-sensitized solar cells (DSSCs) has been investigated. Gadoped ZnO nanorods have been synthesized by an electric-field-assisted wet chemical approach at 80 ̊C. Under a direct current electric field, the nanorods predominantly grow on cathodes. The results of the X-ray ...

A hollow TiO(2) nanoribbon network electrode for dye-sensitized solar cells (DSSC) was fabricated by a biotemplating process combining peptide self-assembly and atomic layer deposition (ALD). An aromatic peptide of diphenylalanine was assembled into a three-dimensional network consisting of highly entangled nanoribbons. A thin TiO(2) layer was deposited at the surface of the peptide template vi...

In this study, dye-sensitized solar cells (DSSCs) were fabricated using nanocrystalline titanium dioxide (TiO2) nanoparticles as photoanode. Photoanode thin films were prepared by doctor blading method with 420 kg/cm2 of mechanical compression process and heat treatment in the air at 500°C for 30 min.

This review focuses on recent advances in microand nano-fabrication techniques and their applications to electrochemical power devices, specifically microfabricated Lithium-ion batteries, enzymatic and microbial fuel cells (biofuel cells), and dye-sensitized solar cells (DSSCs). Although the maturity of these three technologies ranges from market ready (batteries) to fundamental research (biofu...

Electrospinning can be used to prepare nanofibers from various polymers and polymer blends. The adhesion of the substrates on which they are electrospun varies greatly with substrate material structure. In some cases, good is desired produce sandwich structures by electrospinning one directly onto another. This case, e.g., dye-sensitized solar cells (DSSCs). While both pure foil DSSCs have been...
