Eugenic metal-free sensitizers with double anchors for high performance dye-sensitized solar cells.

A series of new phenothiazine-based dyes (HL5-HL7) with double acceptors/anchors have been synthesized and used as the sensitizers for highly efficient dye-sensitized solar cells (DSSCs). Among them, the HL7-based cell exhibits the best efficiency of 8.32% exceeding the N719-based cell (7.

Dye-sensitized solar cells based on (donor-π-acceptor)2 dyes with dithiafulvalene as the donor.

Dipolar metal-free sensitizers (D-π-A; D=donor, π=conjugated bridge, A=acceptor) consisting of a dithiafulvalene (DTF) unit as the electron donor, a benzene, thiophene, or fluorene moiety as the conjugated spacer, and 2-cyanoacrylic acid as the electron acceptor have been synthesized. Dimeric congeners of these dyes, (D-π-A)(2), were also synthesized through iodine-induced dimerization of an appropriate DTF-containing segment. Dye-sensitized solar cells (DSSCs) with the new dyes as the sensitizers have cell efficiencies that range from 2.

High-performance dye-sensitized solar cells based on phenothiazine dyes containing double anchors and thiophene spacers.

A series of new push-pull phenothiazine-based dyes (HL1-HL4) featuring various π spacers (thiophene, 3-hexylthiophene, 4-hexyl-2,2'-bithiophene) and double acceptors/anchors have been synthesized, characterized, and used as sensitizers for dye-sensitized solar cells (DSSCs). Among them, the best conversion efficiency (7.31%) reaches approximately 99% of the N719-based (7.

Use of low-dose topiramate in substance use disorder and bodyweight control.

In recent years topiramate has been used for psychiatric patients, mainly for controlling substance use and food intake. A total of 46 patients who received topiramate treatment during the study period were identified from a computer database. Nineteen had received topiramate for at least 1 month.
