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...

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...

The dyesensitized TiO2 photoelectrodes are tested as photocurrent generators for both water-splitting reactions dye-sensitized solar cells. photoelectrochemical devices furnish effic...

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 ...

In the present study, two new organic dyes based on indigo were prepared and used as sensitizers in dye-sensitized solar cells. To this end, indoxyl was utilized as the electron donor and cyanoacrylic acid as the electron acceptor anchoring groups. These dyes together with their corresponding intermediates were purified and characterized by FTIR, 1HNMR, 13CNMR, elemental analysis and UV-Visible...

ground state geometries have been computed using density functional theory (dft) at b3lyp/6-31g(d,p) level of theory. the excitation energies and spectroscopic parameters have been computed using long range corrected (lc) hybrid functional by time dependent density functional theory (tddft) with lc-blyp level of theory. the polarizable continuum model (pcm) has been used for evaluating bulk sol...

Introduction Dye-sensitized solar cells (DSSCs) are widely recognized as a promising alternative and cost-effective technology for solar-toelectric energy conversion. Current silicon solar cells are limited due to their lack of flexibility, high cost of manufacturing and installation, and heavy weight. Alternatively, dye-sensitized solar cells have a very simple fabrication process, low fabrica...

The dye-sensitized solar cells (DSC) provides a technically and economically credible alternative concept to present day p–n junction photovoltaic devices. In contrast to the conventional systems where the semiconductor assume both the task of light absorption and charge carrier transport the two functions are separated here. Light is absorbed by a sensitizer, which is anchored to the surface o...
