In an expedition for green-energy generation and to lower the cost per watt of solar energy, environmentally friendly biotic colorants were separated from Tectona grandis seeds. The prime colorant in extract is pelargonidin which sensitizes titanium dioxide (TiO2)-based photo anodes. pelargonidin-sensitized TiO2 nanomaterials endured structural, photosensitive, spectral current-voltage interpre...

A novel bis-EDOT-based monomer with ethylene glycol oligomers was synthesized and shown to exhibit strong ion solvation, good transport properties, and effective charge screening. These properties greatly improved J(SC) (4.2 to 7.0 mA cm(-2)) and η (1.6 to 2.9%) in an iodine-free solid state dye-sensitized solar cell (DSSC) employing a Z-907 sensitizer, compared with the corresponding values of...

A new strategy for enhancing the efficiency of TiO2 dye-sensitized solar cells (DSSCs) by doping foreign ion into TiO2 lattice via sol-gel process is reported. DSSCs are based on a semiconductor (i.e., TiO2), formed between a photo-sensitized anode and an electrolyte. In order to reach high conversion efficiency, it is important to increase the electron injection and optical absorption. One pro...

Three new thiophenyl bridged triarylamine-donor based dyes with pyridyl anchoring groups and indolium acceptors have been synthesized studied as sensitizers for the p-type dye-sensitized solar cell (p-DSSC). Compared to known dicyano pyridinium same triarylamine cores, these broadened red-shifted UV–vis absorption spectra, high extinction coefficients extending beyond 700 nm. TD-DFT calculation...

A series of new organic D-pi-A dyes, A1, A2-H and A2-F, possessing a remarkably high absorption extinction coefficient of epsilon > 5.0 x 10(4) M(-1) cm(-1) at peak wavelength were synthesized, among which, A2-F having a key fluorine substitution attains excellent all solid-state DSSC performance, with optimized parameters of eta = 4.86%, J(SC) = 7.52 mA cm(-2), V(OC) = 0.91 V, and FF = 0.71.

Methanol extracts of onion peel waste (Allium cepa) were applied as natural sensitizer in Dye-Sensitized Solar Cell (DSSC) fabrication. This research investigated the dye characteristics extract and its power conversion efficiency. Onion extraction was carried out using unacidified methanol (UME) acidified (AME). Dye absorption characterized by UV-Vis Spectrophotometer at a wavelength 200-800 n...

Abstract Population growth significantly expanding the boundaries of residential areas and living standards for humankind results in a tremendous increase energy consumption. Unlike fossil fuels, which are found only few sites non-renewable sources, solar is renewable freely available every part world. A dye-sensitized cell (DSSC) suitable electrochemical device to harness produce power advanta...

A new T-grafting photosensitizer of Dye-Sensitized Solar Cell (DSSC) has been developed by aligning Donor-Acceptor (D-A) group in an axially chiral BODIPY. Synthesis the dye was conducted over a linear approach involving one-pot, non-oxidative synthesis 1,3,5,7-tetramethyl-8-(o-methoxyphenyl)BODIPY, bromination, and finally C2/C6 ethyl acrylate Pd-Heck coupling to produce 65% 2-ethylacrylic-1,3...
