Dye-sensitized solar cells with an energy storage function are demonstrated by modifying its counter electrode with a poly (vinylidene fluoride)/ZnO nanowire array composite. This simplex device could still function as an ordinary solar cell with a steady photocurrent output even after being fully charged. An energy storage density of 2.14 C g(-1) is achieved, while simultaneously a 3.70% photo...

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...

A series of new phenothiazine-based dyes (HL5-HL7) with double acceptors/anchors have been synthesized and used as the sensitizers for highly efficient dye-sensitized solar cells (DSSCs). Among them, the HL7-based cell exhibits the best efficiency of 8.32% exceeding the N719-based cell (7.35%) by ∼13%.

Based upon the bis(2,9-dimethyl-1,10-phenanthroline)copper(I/II) electron mediator, we present an iodine-free dye-sensitized solar cell exhibiting an impressive power conversion efficiency of 7.0% at 100 mW cm(-2) air mass global (AM1.5G) conditions, which rivals that of a control cell with a conventional iodine redox couple.

A PEDOT-based dye-sensitized solar cell (DSC) is successfully improved by coupling photoelectrochemically deposited PEDOT layer with an Ag paste-paint on the cathode. With a 9.3 μm thick mesoscopic nanocrystalline TiO(2) film, a maximum cell performance of 3.2% with relatively high V(oc) of around 780 mV is achieved.

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...

As a relatively new class of photovoltaic devices with a photoelectrochemical system consisting of a dye-sensitized semiconductor film and an electrolyte, dye-sensitized solar cells (DSSCs) have been regarded as a promising alternative to conventional solid-state semiconductor solar cells. They are relatively cost-effective, are easy to manufacture, and can be readily shaped with flexible subst...

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...

Acknowledgements In the beginning God created the heaven and the earth…….oh wait that was too early . Where do I begin these acknowledgements? Who should I acknowledge? It's 1:57 a.m., I'm in a noffice with no room number, listening to Kanye West, and my mind is wrecked from writing this thesis. The truth is although I'm beaten and tired; the questions of " where do I begin these acknowledgeme...

A dye-sensitized solar cell was constructed using a porphyrin photosensitizer and, in place of the usual iodide redox system, a solution in aniline solvent containing lithium perchlorate electrolyte, camphorsulfonic acid, and poly(ethylene oxide) copolymer. Irradiation generated polyaniline within the cell, initially following a proposed photoelectropolymerization mechanism, and eventually oper...
