DFT Study of Leuco-Indigo and Indigo as Active Material in Dye-Sensitized Solar Cell

Investigation of Indigo/thioindigo Tandem Dye-Sensitized Solar Cells

In this paper we used two free-metal organic dyes (dye 1 and dye 2) based on indigo and thioindigo with cyanoacrylic acid as the electron acceptor group. The proposed dyes were sensitized from naphalene as the starting material by standard reactions and characterized by different analytical techniques and UV-Visible spectroscopy after purification. Spectrophotometric measurements of the organic...

A spectroscopic and DFT study of thiophene-substituted metalloporphyrins as dye-sensitized solar cell dyes.

A combination of density functional theory calculations, electronic absorption and resonance Raman spectroscopy has been applied to a series of beta-substituted zinc porphyrins to elucidate how the substituent affects the electronic structure of the metalloporphyrin and assign the nature of electronic transitions in the visible region. The use of conjugated beta substituents invokes a large per...

Electron Transfer in Dye-Sensitized Nanocrystalline TiO2 Solar Cell

The dye-sensitized solar cells (DSSC) have been regarded as one of the most promising new generation solar cells. Tremendous research efforts have been invested to improve the efficiency of solar energy conversion which is generally determined by the light harvesting efficiency, electron injection efficiency and undesirable electron lifetime. In this review, various characteristics of dye-...

DFT-TDDFT Computational Study of Three Different Chlorophyllous as Dye sensitized solar cells (DSSCs)

Dye sensitized solar cells (DSSCs) are currently attracting widespread academic and commercial interest for the conversion of sunlight into electricity because of their low cost and high DSSCs are similar to natural photosynthesis in the initial processes involving in light-harvesting and charge separation. To gain a better understanding of the role of the sensitizer, particularly of its electr...
