Surface modification with MK-2 organic dye in a ZnO/P3HT hybrid solar cell: Impact on device performance

Synthesis and Investigation of Photovoltaic Properties of New Organic Dye in Solar Cells Device

In this paper, we designed and synthesized free-metal dyes based on indoline. The proposed dyes were synthesized from phenothiazine as the starting material by standard reactions. The chemical structure of the synthesized dye was confirmed using FT-IR, 1HNMR and DSC techniques. Spectrophotometric measurements of the organic dyes in acetonitrile and on a TiO2 substrate ...

Peripheral Hole Acceptor Moieties on an Organic Dye Improve Dye‐Sensitized Solar Cell Performance

Investigation of charge transfer dynamics in dye-sensitized solar cells is of fundamental interest and the control of these dynamics is a key factor for developing more efficient solar cell devices. One possibility for attenuating losses through recombination between injected electrons and oxidized dye molecules is to move the positive charge further away from the metal oxide surface. For this ...

Effects of Sensitization with Natural Pigments on the Performance of Dye-sensitized Solar Cell (DSSC)

Three natural pigments including wild iris, black pomegranate bark and black grapes were used as sensitizer in dye sensitized solar cells (DSSCs) based on TiO2 nanoparticles. The results showed that the DSSC made of black pomegranate bark was more efficient than the other cells due to its strong bonding with TiO2 nanoparticles. Longer electron lifetime, lower electron recombination, and lower...

Effect of Hydroquinone Dderivatives in Electrolytes on Dye-Sensitized Solar Cell Performance

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...
