Sharma, G. D. published the artcileDithienylthienothiadiazole-based organic dye containing two cyanoacrylic acid anchoring units for dye-sensitized solar cells, Recommanded Product: 2,5-Dibromo-3,4-dinitrothiophene, the publication is RSC Advances (2012), 2(30), 11457-11464, database is CAplus.
A new dithienylthienothiadiazole-based organic dye (D) was synthesized by a seven-step synthetic route for use as a sensitizer in dye sensitized solar cells (DSSCs). The dye contains a dithienylthienothiadiazole central unit and two cyanoacrylic acid anchoring side groups. Optical and electrochem. properties of D were evaluated. In addition, d. functional theory (DFT) and time dependent d. functional theory (TD-DFT) calculations were carried out. A favorable electronic excitation from the HOMO (HOMO) to the LUMO (LUMO) indicated that the dye can be used as a sensitizer for DSSC applications. The photovoltaic properties of laboratory scale optimized DSSCs sensitized with D showed a power conversion efficiency (PCE) of 4.22%, which was further improved to 5.47% upon the addition of chenodeoxylic acid (CDCA) as a coadsorbant.
