Synthesis and characterization of conjugated polymers with main-chain donors and pendent acceptors for dye-sensitized solar cells

Herein, we report three conjugated polymers with main-chain donors and pendent π-acceptors as photosensitizers for dye-sensitized solar cells (DSSCs). The polymer PPTZF (which contains a phenothiazine (PTZ) chromophore and has a 9,9-dioctyl-fluorene (F) group as the donor unit in the main chain and a cyanoacrylic acid acceptor in the side chain, linked by a thiophene unit) was used as a basic structure. Then 9,9-dioctyl-carbazole (CZ) and triphenylamine (TPA) were selected to replace F and PTZ, respectively, as structural modifications to get another two polymers: PPTZCZ and PTPACZ. Finally, we fabricated devices and examined the effects of different donors with flexible alkyl chains on the photovoltaic performance of DSSCs. Our studies have revealed that the PTPACZ dye, which has a degree of polymerization (DP) of ～4, exhibited excellent photovoltaic performance with a relatively high power conversion efficiency of 4.4% under standard (Global Air Mass 1.5) illumination. Charge extraction and transient photovoltage decay measurements have demonstrated that the charge recombination lifetime (τ) is a crucial influencing factor on the open-circuit voltage of these polymer dyes.

Anti-recombination organic dyes containing dendritic triphenylamine moieties for high open-circuit voltage of DSSCs

Three novel sensitizers with dendritic triphenylamine moieties were synthesized and used for dye-sensitized solar cells (DSSCs). Their absorption spectra, electrochemical and photovoltaic properties were extensively investigated. All three DSSCs exhibit high open-circuit voltage over 0.8 V. The photovoltaic results indicate that the dendritic triphenylamine units improve the open-circuit voltage, which is attributed to the retardation of charge recombination, demonstrating that non-planar and larger molecules exert better blocking function. Under standard global AM 1.5 solar conditions, the best performance of the DSSCs exhibits a short-circuit current density of 10.35 mA cm-2, an open-circuit voltage of 0.836 V and a fill factor of 0.68, corresponding to an overall conversion efficiency of 5.87%.

Poly (triphenylamine-fluorenylmethylchloroformate) dye and its application

The invention discloses a poly(triphenylamine-fluorene) dye and its application. The poly(triphenylamine-fluorene) dye is prepared through a Stille coupling reaction of a monomer having a triphenylamine structure and a monomer having a fluorene structure. The prepared poly(triphenylamine-fluorene) dye has a triphenylamine and fluorene composite donor unit structure, and can be applied in the production of dye-sensitized solar cells in order to obtain dye-sensitized solar cells with high current density and high photoelectric conversion rate.
