Organic Dye and Dye-Sensitized Solar Cell

PURPOSE: An organic dye, photoelectric diode including the same and dye-sensitized solar battery are provided to have an absorbing band in long wavelength. CONSTITUTION: An organic dye is represented by chemical formula 1. A photoelectric diode includes porous oxide semiconductor membrane which includes the organic dye. A dye-sensitized solar cell comprises a first electrode, a second electrode which is formed on one side of the first electrode and includes a light absorptive layer, and electrolyte buried in a space between the first and second electrodes.

Conjugated polymers with repeated sequences of group 16 heterocycles synthesized through catalyst-transfer polycondensation

Periodic π-conjugated polymers of the group 16 heterocycles (furan, thiophene, and selenophene) were synthesized with controlled chain lengths and relatively low dispersities using catalyst-transfer polycondensation. The optical gap and redox potentials of these copolymers were fine-tuned by altering the heterocycle sequence, and atomic force microscopy revealed nanofibrillar morphologies for all the materials. Grazing incidence wide-angle X-ray scattering of the thiophene-selenophene copolymers indicated that the π-stacking distance increased with incorporation of the larger heteroatom (from ～3.7-4.0 ?), while the lamellar spacing decreased (from ～15.8-15.2 ?). The study also revealed that periodic sequences allow electronic properties to be tuned while retaining nanofibrillar morphologies similar to those observed for poly(3-hexylthiophene).

Dye-functionalized head-to-tail coupled oligo(3-hexylthiophenes) - Perylene-oligothiophene dyads for photovoltaic applications

A series of novel donor-acceptor systems, consisting of head-to-tail coupled oligo(3-hexylthiophene)s covalently linked to perylenemonoimide, is described. These hybrid molecules, which differ by the length of the oligothiophene units from a monothiophene up to an octathiophene, were created via effective palladium-catalyzed Negishi and Suzuki cross-coupling reactions in good to excellent yields. The optical and electrochemical properties of these compounds were determined and based on this series structure-property relationships have been established which give vital information for the fabrication of photovoltaic devices. Because the synthesized perylenyl-oligothiophenes distinguish themselves by a high absorption between 300 and 550 nm and an almost complete fluorescence quenching of the perylene acceptor, they meet the requirements for organic solar cells.
