Synthesis and investigation of triphenylamine-based double branched organic dyes for p-type dye-sensitized solar cells

Two double branched organic dyes (T1I and T2I) were synthesized, characterized, and employed as photosensitizers in p-type dye-sensitized solar cells (p-DSSC); we have compared with corresponding single branched dye (TC1) and reference dye P1. The absorbance of the dyes in solution was red shifted and the oxidation potential gradually decreased with increasing the donating ability. It was found that modification from single branched (TC1) to double branched (T1I and T2I) system resulted in increased photocurrent density leading to the higher photovoltaic performances. The charge transporting ability is increased with the introduction of double branching, as evidenced from electrochemical impedance analysis.

A fast-response electrochromic device based on a composite gel film comprising triphenylamine derivatives and WO3

To obtain an electrochromic device with a quick response and multicolor change,N,N′-(4-((3-(triethoxysilyl)propyl)imino)methyl)phenyl-N,N′-diphenyl-4,4′-biphenyl-diamine (TPB-PSSO) containing a tetraphenylbenzidine (TPB) unit and siloxane group was synthesized, and its electrochromic properties were investigated. Using the TPB-PSSO gel film and a WO3/TPB-PSSO gel film as active materials, electrochromic devices (ECDs) having the structures indium tin oxide (ITO)/TPB-PSSO gel film/ITO and ITO/WO3film/TPB-PSSO gel film/ITO, respectively, were prepared. These two devices exhibited a fast response according to chronoamperometry measurements, with coloring and bleaching times of 4 and 9 ms and 5 and 5 ms, respectively.
