Three different carbon-based counter electrodes are investigated in light of catalytic activities such as electrochemical frequencies and interface impedances. We fabricated carbon-based counter electrodes of dye-sensitized solar cells [DSSCs] using graphene, single-walled carbon nanotubes [SWNTs], and graphene-SWNT composites by electrophoretic deposition method. We observed the optical and el...

Dye sensitized solar cell was fabricated from a double layer photoanode. First, TiO2 nanoparticles  were synthesized by hydrothermal method. These TiO2 NPs were deposited on FTO glasses by electrophoretic deposition  method in applied voltage of 5 V and EPD time of 2.5-10 min. Then TiO2 hollow spheres (HSs) were synthesized by sacrificed template method with Carbon Spheres as template and TTIP ...

Abstract Dye-sensitized solar cells (DSSC) have recently gained significant attention in a number of markets and are recognized as better option for energy generation than conventional ones, providing clean, sustainable, renewable green energy. Several studies focused on photoanode optimization using machine learning. Photoanode produces performance results the form Voc Isc, which then used mod...

A variety of methods are available for creating the titanium dioxide (TiO2) semiconductor surface layer of dye-sensitized solar cells (DSSCs); however, many of them are used independently to create surface morphologies that are influenced by only one process. A series of experimental techniques are utilized, some not originally used for thin film preparation, to create a semiconductor surface t...

A homologous series of fire-retardant oligoalkyleneoxy-phosphates was synthesized for evaluation as liquid or gel-type electrolyte media for dye-sensitized solar cells (DSSCs) and secondary lithium batteries. Unoptimized DSSC electrolyte formulations for DSSCs achieved ionic conductivities as high as 5.71 × 10(-3) S · cm(-1) and DSSC test-cell efficiencies up to 3.6% as well as Voc, Jsc, and ff...

Dye-sensitized solar cell (DSSC) is one of the promising photovoltaic (PV) technologies for applications requiring high aesthetic features combined with energy production such as building integration PV (BIPV). In this context, DSSCs have ability to be wavelength selective, thanks development new sensitizers by molecular engineering. The long history dye research has afforded technology differe...

Multi-walled carbon nanotube (MWCNT)/TiO2 mesoporous networks can be employed as a new alternative photoanode in dye-sensitized solar cells (DSSCs). By using the MWCNT/TiO2 mesoporous as photoanodes in DSSC, we demonstrate that the MWCNT/TiO2 mesoporous photoanode is promising alternative to standard FTO/TiO2 mesoporous based DSSC due to larger specific surface area and high electrochemical act...

Dye-sensitized solar cells have shown great potential in low and self-powered nano/micro-scale applications, due to their fabrication costs, semi-transparency the visible spectrum, diffused light harvesting capabilities, lead-free structure. However, DSSC efficiencies are still relatively limited absorption capabilities active mesoporous layer. The current study demonstrates an attempt boost ov...

In the current study, pure TiO2 and Cr-doped TiO2 (Cr@TiO2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous TiO2 electrodes for dye-sensitized solar cells (DSSCs). It is hypothesized that the advantages of the doping of the metal ions into TiO2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...
