Synthesis and Application of Two Organic Dyes for Dye-Sensitized Solar Cells

Synthesis and Application of Two Organic Dyes Based on Indoline in Dye-Sensitized Solar Cells

In this paper we sensitized two new organic days dye 1 and dye 2 based on thioindigo with phenothiazine as the electron donor group. We used acrylic acid and cyanoacrylic acid as the electron acceptor anchoring group in dye 1 and dye 2 respectively. The proposed dyes were sensitized from phenothiazine as the starting material by standard reactions and characterized by different techniques such ...

Synthesis of Alkyl-functionalized Organic Dyes and Their Application to Dye Sensitized Solar Cells (DSSCs)

Ruthenium dye-based dye-sensitized solar cells (DSSCs) have received great deal of attraction from chemists and material scientists because of their over 10% of photon to current conversion efficiency. The high cost and much synthetic efforts of ruthenium dyes, nevertheless, has often been reported as problematic. Recently, organic dye-based DSSCs whose photon to current conversion efficiency a...

Novel organic dyes for efficient dye-sensitized solar cells.

Two novel metal-free organic dyes containing thienothiophene and thiophene segments have been synthesized. Nano-crystalline TiO2 dye-sensitized solar cells were fabricated using these dyes as light-harvesting sensitizers, and a high solar energy-to-electricity conversion efficiency of 6.23% was achieved.

Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

Natural dyes extracted from black carrot and bramble for Dye-Sensitized Solar Cells

Two different natural dyes containing anthocyanin extracted from black carrot and bramble from Iran. Spectrophotometric evaluations of the natural dyes in solution and on a TiO2 substrate were carried out in order to assess changes in the status of the natural dyes. The results show that the natural dyes indicate buthochromic shift on the TiO2 substrates. The chemical adsorption of natural dyes...

Acid azo dyes for efficient molecular photovoltaic: study of dye-sensitized solar cells performance

In this paper we sensitized three free-metal azo days Dye 1, Dye 2 and Dye 3 based on 1,8-naphthalimide with n-propyl as the electron donor group. We used sulfonic acid and hydroxyl substituents as the electron acceptor anchoring group in synthesized dyes. The proposed dyes were sensitized from acenaphthene as the starting material by standard reactions and characterized by different techniques...
