Two series (Cy and An) of dyes containing a cyanovinyl entity and an anthracene with alkoxy substituents at the 9 and 10 positions, respectively, as the spacer have been synthesized and characterized. Dye-sensitized solar cells (DSSCs) using these dyes as the sensitizers exhibited good efficiencies. The efficiencies of the devices based on Cy series range from 3.48-4.92%, and those based on An series range from 4.17-4.69%. These values which reach 45-70% and 59-67%, respectively, with respect to that of N719-based device fabricated under similar conditions. In general, a better DSSC performance was achieved in molecules with a shorter molecular structure and higher light harvesting. The cyanovinyl entity (Cy series), especially in the long molecular structure, where the cyanovinyl group is away from the electron donating amine by two or more aromatic groups, may behave as a charge trap. This argument was supported by theoretical computations. A positive correlation could be obtained from the theoretically calculated product of oscillator strengths and the charge shift at the cyanoacrylic acid group and the short-circuit currents in the DSSCs. The rigid anthracene segment in An series compounds. The anthracene with alkoxy substituents may cause thiophene moiety hamper the charge transfer and results in lower open-circuit voltages and short-circuit currents of the solar cells.

Recent years due to extensive use of fossil fuels, we can imagine in the next few decades, fossil fuels will be exhausted one day. Due to the severe impact brought by “energy crisis”, it is inevitable to discover and develop renewable energy. Among all of the renewable energy, solar energy is the center of attention and it will be the future trend. Wherein Dye-Sensitize solar cells due to its low production cost, flexibility, large industrial potential and large-scale production, thus, it gets extremely attention and high hopes. In the design of this study was to investigate the two functional groups with organic dye amine. Using the method of synthesis of furan derivatives subject and using Suzuki-Miyaura coupling reaction of synthesis coupled with amine functional groups, and will have the effect of electron donating and with an electron-withdrawing effect of the molecule doped into the body which, to increase the charge transfer on the body and increase its spectral absorption range, while on the other side chain embedded with thiophene molecule material can be used to adjust the material bands, enhance its properties, and increase their solar photons absorption ability and then transform the electron on TiO¬2. The study intends to generate several amine group dye structure utilizes low band gap and photon characteristics in two dimension D-π-A system. This study intends to design two structures with amine dye molecules which poses superior light absorption ability, so in the design of two-dimensional structure of dye can control HOMO and LUMO energy level individually. Therefore, the appropriate energy levels can be regulated and an electrolyte to coordinate with TiO¬2 and improve their conditions of the stack structure which can be significantly improved electron transfer between molecules and molecules.

In this study, we designed a series of metal-free dye-sensitized solar cell (DSSC) organic dyes with star-shaped system ((EDG1)2-EDG2-π-EWG), incorporating with different moiety, such as auxiliary electron-donating groups (EDG1), mainly electron-donating group (EDG2), π-conjugated linker moiety and electron-withdrawing groups (EWG). Our calculated results were calculated by the density functional theory (DFT/B3LYP) and time-dependent density functional theory method with 6-31G(d) basis set. Our calculated results exhibited a good agreement with experimental data. In different EDG1 system, the stronger auxiliary electron-donating groups can make an effect to influence the molecular to get higher EHOMO, large absorption wavelength, large the free energy change for the electron injection, and longer lifetime. These calculated results of designed molecules show that the TPA series of PY and the DPBF series of DPP have a better performance, and may be used as potential sensitizers in the DSSC application. In different EWG system, the stronger acceptor groups can make an effect to influence the molecular to get lower ELUMO, smaller open circuit voltage. Moreover, when the molecular transition configurations is effective charge transfer excitation, electron distribution extend to anchoring group of dye, electron will injected efficiently to TiO¬2. These calculated results of designed molecules show that the TPA and DPBF series of C have a better performance, and may be used as potential sensitizers in the DSSC application.

New organic dyes were developed and used as the sensitizers for the dye-sensitized solar cells (DSSCs). Different approaches (co-sensitized, co-adsorbent, zinc oxide photoanode) were used to improve the cell performance. Various physical measurements, including UV–vis absorption spectroscopy, electrochemical impedance spectroscopy (EIS), and incident photo–to–current conversion efficiency (IPCE) spectra, charge extraction method (CEM) and intensity-modulated photovoltage spectroscopy (IMVS) were used to obtain important parameters relevant to the cell performance for correlation between the molecular structure and the cell performance. Bipolar organic dyes containing a 9,10-dihydrophenanthrene entity in the conjugated bridge were synthesized as the sensitizers for DSSCs. The DSSC exhibits good cell efficiencies ranging from 5.21% to 5.95% under 1 sun condition. When combining the best performed dye (BP-2) with a squaraine dye (SQ2), the efficiency increment of the co-sensitized DSSCs is in compliance with the increased ratio of BP-2/SQ2. The co-sensitized DSSC in which the ratio of BP-2 and SQ2 was 8:2 (v/v) exhibited a high efficiency of 8.14%. The TiO2 film adsorbed with co-sensitizers was subjected to Auger electron spectroscopy (AES) for probing the dye distribution across the TiO2 film depth. We synthesized benzothiadiazole (BT)-containing sensitizers with BT entity directly connected to 2-cyanoacrylic acid for DSSCs using ZnO as the photoanode aiming at better charge separation because of better electron transport. The cells performed better than those using TiO2 as the photoanode. The cell efficiency can be further improved when a newly developed brush hierarchical ZnO nanoplates were used as the light back scattering layer (SL) of the cell. Dyes consisting of 2,6-conjugated anthracene segment as the conjugated spacer, 9,10-bishexyloxyanthracen-phenylamino as the electron donor, and cyanoacrylic acid as the acceptor and anchor as well were synthesized. DSSCs using these sensitizers exhibited efficiencies 4.69&;#8722;7.52% under AM 1.5 illumination, and an impressively high efficiency (9.11%) surpassing the N719-based standard cell has also been achieved with the use of CDCA co-adsorbent. In order to enhance electron injection and dark current suppression, the dyes with two anchoring groups, D-π-(A)2, were synthesized from a 2,3,5-substituted thiophene motif. These dyes exhibit high molar extinction coefficient and good power conversion efficiency of the cells. With addition of co-adsorbent, CDCA, the device performance of all the DA-based DSSCs were improved by 1.03 to 2-fold, with the best efficiency reaching 95% of the N719-based standard cell (8.28%).
