Abstract: Dye-sensitized solar cells (DSSC) have drawn much attention due to their higher versatility and lower production cost compared to inorganic photovoltaics. The top performers of DSSC have achieved power conversion efficiency over 10%, which is comparable to amorphous silicon solar cells. In this work, new photosensitizers and nanostructure for improving the photovoltaic performance of DSSC were developed and evaluated. Two series of cyclometalated ruthenium(II) complex photosensitizer were presented and their photosensitizing properties in DSSC were studied. Eight cyclometalated ruthenium(II) terpyridine complexes with three carboxylic acid groups on the terpyridine ligand were synthesized. Series A (M1 to M4) consist of C, N, N' ligands substituted with phenyl group whereas series B (M5 to M8) consist of C, N, N' ligands substituted with m-fluorophenyl group. All of the complexes exhibited broad aborption spectra covering the whole visible spectrum. The complexes in series B generally showed better photovoltaic performance than those in series A in the DSSCs. DSSC fabricated from M7 achieved the highest Voc, Jsc and power conversion efficiency among other DSSC, which were 0.56 V, 7.30 mAcm-2 and 2.63 % respectively. Truxene-core donor--acceptor dyes were presented and their photosensitizing properties in DSSC were studied. Eight dyes with either one donor two acceptors system (T2, B2, T2R and B2R) or two donor one acceptor system (T1, B1, T1R and B1R) were synthesized. Dyes with two acceptors have high molar extinction coefficients originated from the charge-transfer transition band, which are almost two times higher than those with only one accceptors. Both the enhanced absorption and better anchoring geometry on TiO2 contribute to the better photovoltaic performance of the two acceptors dyes in the DSSCs. Devices fabricated from B2 and volatile solvent electrolyte exhibited the best photovoltaic performance among the truxene-core dyes. The Voc, Jsc, FF and power conversion efficiency of the device were 0.59 V, 9.69 mAcm-2, 0.63 and 3.62 % respectively. Dyes based on cyanoacrylic acid anchoring groups (T1, T2, B1 and B2) were found to perform better than those based on rhodanine-3-acetic acid dyes (T1R, T2R, B1R and B2R) in both donor--acceptor configurations. ITO nanorod/TiO2 nanoparticle composite films with the three different types of ITO nanorod with different length (150 nm, 600 nm and 1.5 μm) were fabricated on FTO glass substrate. The transmittance and sheet resistance of the ITO nanorod array on the FTO glass substrate were found decreased with increasing the length of the ITO nanorod. When the ITO nanorod/TiO2 nanoparticle composite films were applied as the anode in DSSCs, the device fabricated from 600 nm ITO nanorod with TiO2 'double layer' film showed enhanced photocurrent generation. The improved photocurrent generation is suggested to be due to an improved charge collection efficiency at the ITO nanorod back electrode.

This book was released on 2016 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Finding alternative energy sources is one of the great problems of science today. One potential solution, the dye-sensitized solar cell (DSSC) has been studied thoroughly since its discovery in 1991. They are composed of a sensitizing dye adsorbed on to the surface of a semiconducting metal oxide. Much research has been done trying to improve the DSSC efficiency, mainly by creating new derivatives of the sensitizing dye. However, despite the large number of derivatives made, most have utilized the same strategy of extending conjugation to increase overall efficiency. In this work, I investigated a different class of compounds, the dibenzo[b, j][1,10]phenanthrolines, which highlight the effect of extended aromaticity on the properties of ruthenium-based DSSCs. First, I developed a synthetic scheme which improves upon those used before, opening up the possibility of creating a library of compounds to be used for future investigations. Second, the chemistry of these compounds was investigated, which was shown to be different from the [1,10]phenanthrolines. Specifically, they were shown to be more sensitive to oxidative, reductive, and alkaline conditions, along with being more resistant to formation via the Pd-catalyzed dehydrogenation. Finally, these compounds were evaluated for their ability to form a DSSC, showing low conversion efficiencies, but with promise for better results in the future. This lays the groundwork for the creation of a library of DSSCs based on this backbone. As well, we report the creation of color-changing dye-sensitized solar cells (DSSCs) using N-propanoic functionalized spiropyrans and spirooxazines. We investigated the photophysical properties of these compounds in various solvents and pH conditions using UV-Vis spectroscopy, and their behavior on a TiO2 surface using a combination of UV-Vis and FT-IR. Their performance as sensitizing dyes for DSSCs was analyzed. This study reveals a number of properties for this class of compounds that affect their performance as both photochromic compounds and DSSC sensitizers, which allow for future creation of an efficient photochromic DSSC.

This book was released on 2020-09-10 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis provides the necessary experimental and analytical tools to unambiguously observe the atomically resolved chemical reactions. A great challenge of modern science has been to directly observe atomic motions during structural transitions, and while this was first achieved through a major advance in electron source brightness, the information content was still limited and new methods for image reconstruction using femtosecond electron diffraction methods were needed. One particular challenge lay in reconciling the innumerable possible nuclear configurations with the observation of chemical reaction mechanisms that reproducibly give the same kind of chemistry for large classes of molecules. The author shows that there is a simple solution that occurs during barrier crossing in which the highly anharmonic potential at that point in nuclear rearrangements couples high- and low-frequency vibrational modes to give highly localized nuclear motions, reducing hundreds of potential degrees of freedom to just a few key modes. Specific examples are given in this thesis, including two photoinduced phase transitions in an organic system, a ring closure reaction, and two direct observations of nuclear reorganization driven by spin transitions. The emerging field of structural dynamics promises to change the way we think about the physics of chemistry and this thesis provides tools to make it happen.
