This book was released on 2017 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potential of environmentally friendly solar energy is enormous, but the fabrication of solar cells that are efficient and competitive to other sources of energy remains a serious challenge. The quantum dot sensitized solar cells (QDSSC) is an encouraging cost-effective option to study as it has the potential to overcome the maximum theoretical limit of traditional solar cells. The key components in QDSSCs is the quantum dot/photoanode heterostructure. So, the study of optical properties of quantum dots and photoanode materials, and the charge transfer at the interface is necessary to understand and improve the efficiency and durability of these solar cells. Zinc Tin Oxide (ZTO) has potential for use as a photoanode in QDSSCs. So, the optical properties of ZTO nanowires was studied by using diffuse reflectance, Photoluminescence(PL), and Time Resolved PL (TRPL) measurements. The ZTO nanowires have a direct forbidden transition and thus do not have band to band PL. The two distinct PL peaks observed are centered at 1.86eV (red) and 2.81eV (blue), representing two distinct defect state transitions. The time resolved PL measurements show complex non-exponential decays at all wavelengths, indicative of defect to defect transitions, with the red emissive states decaying much slower than the blue emissive states. We propose an energy band model for the nanowires and the associated transitions between the defect states that are consistent with our measurements. One of the goal of this dissertation is to study the effect of Mn doping on ZTO and the electron transfer from CdSe QDs to Mn ZTO nanoparticles. We have successfully synthesized high surface area & single phase ZTO and Mn doped ZTO NPs using hydrothermal synthesis method. The incorporation of Mn into the ZTO has been studied by using XRD, TEM and XPS. We find that the Mn2+ ion most likely substitutes for the Zn2+ ion in the ZTO crystal. The Mn doping not only changes the magnetic properties, but also modifies the optical properties of ZTO nanoparticles. It modifies the band gap energy, changes the band tail states, and creates mid-band gap states as depicted in absorbance spectra. In addition, the Mn doping in ZTO quenches the defect PL in the ZTO nanoparticles. Finally, we sensitized ZTO and Mn ZTO nanoparticles films with CdSe quantum dots to form CdSe/ZTO and CdSe/Mn ZTO nanoparticle interfaces. A comparative electron transfer study is conducted in CdSe/Mn ZTO and CdSe/ZTO interface using fs transient absorption. Our result suggests that the electron transfer from CdSe is a not a single step process, but instead involves the intermediate charge transfer state. The faster time constant is associated with charge transfer and is found to be 2 ps and 3.7 ps in CdSe/ZTO and CdSe/Mn ZTO samples, respectively. The slower time constant is due to charge dissociation and occurs on a time scale of 28 ps and 30 ps in CdSe/ZTO and CdSe/Mn ZTO, respectively. The observed electron transfers differences due to the Mn doping in the ZTO nanoparticles has been analyzed using the Marcus theory of electron transfer, considering the effect of driving force and sub band gap states on the transfer rate, and agrees with our measurements.

Available in PDF, EPUB and Kindle. Book excerpt: Energy crises and global warming pose serious challenges to researchers in their attempt to develop a sustainable society for the future. Solar energy conversion is a remarkable, clean, and sustainable way to nullify the effects of fossil fuels. The findings of photocatalytic hydrogen production (PCHP) by Fujishima and Honda propose that “water will be the coal for the future”. Hydrogen is a carbon-free clean fuel with a high specific energy of combustion. Titanium oxide (TiO2), graphitic-carbon nitride (g-C3N4) and cadmium sulfide (CdS) are three pillars of water splitting photocatalysts owing to their superior electronic and optical properties. Tremendous research efforts have been made in recent years to fabricate visible or solar-light, active photocatalysts. The significant features of various oxide, sulfide, and carbon based photocatalysts for cost-effective hydrogen production are presented in this Special Issue. The insights of sacrificial agents on the hydrogen production efficiency of catalysts are also presented in this issue.

Book excerpt: The Chlorophylls reviews developments in study of chlorophylls, and at the same time summarizes the state of knowledge in the more established areas of the physics, chemistry, and biology of chlorophylls. The book is organized into four sections. The first section deals with the chlorophylls as chemical entities, and treats their isolation, analysis, chemistry, and synthesis. The second concerns chlorophylls in real and colloidal solution and in the solid state in vitro, and includes the effects of aggregation on visible, infrared, and NMR spectral properties. The third section treats the biosynthesis, organization, and properties of chlorophylls in the plant and bacterial cell, and the fourth is concerned with the photochemical and photophysical behavior of chlorophylls in vitro and in vivo. It is hoped that this work will help those investigating selected aspects of chlorophyll to keep abreast of other methods and approaches, and will provide the interested scientist with a modern, conceptually organized treatment of the subject.

Download or read book Heterogenous Photochemical Electron Transfer written by Michael Gratzel and published by CRC Press. This book was released on 2018-01-18 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph attempts to unify these diverse and exciting new developments within a common framework. First, the physical principles underlying heterogenous electron-transfer processes are outlined in a concise way and are compared to the homogeneous counterpart. This analysis includes the notion of the Fermi level in liquids and solids as well as the distribution of electronic energy levels in solids and liquids. A comparison is made between the salient kinetic features of homogeneous and heterogeneous electron transfer reactions. This establishes the basis for the subsequent treatment of the transduction of excitation energy and photo-initiated electron transfer in organized molecular assemblies, such as micelles, vesicles and monolayers. Transmembrane redox processes are critically reviewed. Particular attention is given to semiconductor electrodes and particles. This includes a discussion of quantum size effects, the nature of space charge layers as well as surface states and the dynamics of charge carrier-induced redox reactions at the semiconductor solution interface. These processes are of fundamental importance in such diverse fields as photochromism, electrochromic displays, electroreprography and photography, information storage, photocatalysis, photodegradation of paints, and solar energy conversion.
