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

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

In the present study, two new organic dyes based on indigo were prepared and used as sensitizers in dye-sensitized solar cells. To this end, indoxyl was utilized as the electron donor and cyanoacrylic acid as the electron acceptor anchoring groups. These dyes together with their corresponding intermediates were purified and characterized by FTIR, 1HNMR, 13CNMR, elemental analysis and UV-Visible...

Solution-processed organic photovoltaics based on indoline dye molecules developed in dye-sensitized solar cells.

A donor-acceptor (D-A) type indoline dye, D149, was used as an electron donor in solution-processed organic solar cells (OSCs). For bulk-heterojunction (BHJ) type OSCs with PC70BM as electron acceptor, the power conversion efficiency (PCE) is sensitive to the amount of D149 in the D149/PC70BM blend film. When the concentration of D149 in the blend film was as low as 5%, the highest PCE of up to...

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.

New Triphenylamine-Based Dyes for Dye-Sensitized Solar Cells

A series of new conjugated metal-free organic dyes (TC1, TC2, TC3, and TC4) comprising triphenylamine (TPA) moieties as the electron donor and cyanoacetic acid moieties as the electron acceptor/anchoring groups were designed at the molecular level and developed for the use in dye-sensitized solar cells (DSCs). Quantum chemical calculations have been performed to gain insight into structural, el...
