New kinds of hydroquinone derivatives were synthesized and along with a azo dye applied as additives in the iodide/iodine redox electrolyte for dye-sensitized solar cells and their effect on the short-circuit photocurrent of dye sensitized solar cells was investigated. Addition of 0.05 M a hydroquinone derivative in the electrolyte comprising 0.5 M 1-methyl-3-propylimidazolium iodide (MPII) and...
The counter electrode (CE) containing catalyst layer and transparent conducting oxide (TCO) is by far the most expensive components in Dye sensitized solar cells (DSSC) due to use of rare earth element such as Pt. potential replacement both TCO Pt-based would essentially pave way mass commercialization technology DSSC. In this investigation, an attempt has been made replace Pt with a single del...
Here we report the fabrication of highly transparent graphene oxide (GO) reinforced TiO2 nanocomposite thin film and demonstrate that it enhances power conversion efficiency dye-sensitized solar cells (DSSC) when used as photoanode. TiO2-GO films with varying GO concentrations are deposited on top fluorine doped tin (FTO) coated glass substrate by easy, cost-effective sol-gel spin coating techn...
A series of quinoidal thiophene based dye molecules were designed and their optoelectronic properties were studied for dye sensitized solar cell (DSSC) applications. The efficiency of the designed dye molecules was analyzed using various parameters such as the HOMO-LUMO energy gap, absorption spectra, light harvesting efficiency (LHE), exciton biding energy (Eb) and free energy change for elect...
Ruthenium N719 is a well-known material used as the dye in commercial dye-sensitized solar cell (DSSC) devices. However, it poses risks to human health and environment over time. On other hand, titanium dioxide (TiO2) has low electron mobility high recombination losses when photoanode this photovoltaic technology device. In addition, using harms health. As an alternative sensitizer compensate o...
One of the possibilities to mass-produce dye-sensitized solar cell (DSSC) device is if it could be embedded to the area atop metal roof. However, the use of metal substrate is constrained by the corrosion caused by the electrolyte solution used in the DSSC device such as iodide/tri-iodide (I-/I3-). In this study, we propose the utilization of polyaniline/reduced graphene o...
We propose the concept of structured single-walled carbon nanotubes (SWNTs) for the applications of heterojunction solar cells and dye-sensitized solar cells (DSSCs). The structure of SWNTs was controlled and modified by a simple water vapor treatment, which was originally developed by our group. Compared with the graphene-Si solar cell and the SWNT-Si solar cell using the random-oriented SWNT ...
For dye-sensitized solar cells (DSSC), the fundamental process that determines the maximum short-circuit current is the absorption of light. In such devices, this is produced by the concurrent phenomena of light absorption by dye molecules and light trapping in the mesoporous, titania photoanode structure. The decoupling of these two phenomena is important for device characterization and the de...
in this study, the tio2 nanorods were synthesized from p25 tio2 nanoparticles by hydrothermal method in 10 m naoh solution. the effects of annealing temperatures on produced nanorods were investigated by scanning electron microscopy (sem) x-ray diffraction (xrd) and photoluminescence (pl) spectroscopy. diameter growth and changes of surface oxygen defects of synthesized nanorods are stu...
