This thesis concerns the study of D–π–A type dyes as sensitizers for NiO-based p-type dye-sensitized solar cells. The focus has been on the design and synthesis of efficient dyes and the identification of parameters limiting the solar cell performance. We have developed a new design strategy for the dyes: upon photoexcitation of the dye, the electron density is moving from the part that is attached to the semiconductor towards the part which is pointing away. This intramolecular charge transfer provides an efficient pathway for the following charge transfer processes. The first organic dye, co

The objective of this research was to study the adsorption and photodegradation of crystal violet (CV) dye by using poly(2-hydroxyethylmethacrylate) (PHEMA) hydrogel and nanocomposite TiO2-PHEMA hydrogel. Since the TiO2 nanoparticle has poor solubility, another goal of this study was to make a uniform TiO2 nanocomposite gel. These gels can be used in water treatment and can be easily photodegrade by exposure of sunlight which is similar to exposing to UV-vis. PHEMA was synthesized by free radical polymerization. The nanocomposite gels were characterized by FT-IR and XRD to confirm the presence

Abstract:

Up to now, the market of solar cells has been dominated by the conventional silicon devices. Recently, a new class of solar cells, known as dye-sensitised solar cells (DSSCs) have emerged. They are based on the hybrid chromophore/TiO2 semiconductor interface, and the low cost of manufacturing and the flexibility make them a very promising alternative to the traditional silicon cells. With this thesis, we aim at investigating theoretically, by means of density functional theory atomistic simulations, some of the current challenges in DSSCs. In particular, we will focus on the binding mode of th

This thesis presents two models of a dye-sensitized solar cell (DSC): diffusion model and electrical model. The main purpose is to investigate interfacial charge transfer and charge transport within the semiconductor/electrolyte layer under illuminated conditions. These two interrelated models confirm that diffusion is the major driving force for electron and ion transport, while the drift of electrons is negligible. The diffusion model was utilized to simulate the temperature influence on the overall efficiency of DSC with a consideration of the voltage loss at titanium dioxide (TiO2)/ tra

Abstract:

The pure organic dye sensitized solar cells (DSSCs) were studied and a new organic dye of donor-π-2acceptors (D-π-2A configuration) was fabricated. This dye, denoted as B2, was investigated and applied in DSSCs. Density functional theory (DFT) was used to examine the electronic distribution of the frontier orbitals of the B2 dye. It was found that intramolecular charge transfer (ICT) between the donor moieties and acceptor moieties of the B2 dye may take place under photo irradiation. The LUMO, LUMO+1 and LUMO+2 of B2 are all distributed on the acceptor moieties and this is very helpful to enh

碩士<br>義守大學<br>生物技術與化學工程研究所碩士班<br>97<br>The aim of this study is developing efficient and stable dye sensitized solar cells. We focus on the development of the following two key materials: 1. the organic dyes do not contain noble metals; 2.high specific surface area nanocrystalline TiO2 electrodes. In the part of dyes, we have designed and synthesized the Azo dye having absorption of short wavelength, and mixed it with the Cyanine dye having absorption of long wavelength instead of single dye system to utilize the broad spectrum of sunlight. The performances of DSSCs fabricated in the mixed dye

Abstract:

In this work it has been attempted for the first time to investigate the complete working electrode (half cell interface: TiO2/dye/electrolyte) of the Dye Sensitized Solar Cell (DSSC) by means of photoelectron spectroscopy. The scope of this work is to investigate the interfacial interactions between the adsorbates and the TiO2 substrate, rather than bulk processes within the substrate or electrolyte. Since the coverage of the dye onto the TiO2 substrate amounts only up to one monolayer, a highly surface sensitive method, as Synchrotron Induced Photoelectron Spectroscopy (SXPS), has been appli

According to above-mentioned four points, because the cost and application are limited to the material problem in the traditional PV Cell, it is unable to get good improvement. Observe Dye-sensitized Solar Cells, because of its congenital advantage, the production cost is low and the application is extensive too, only efficiency and stability has not got good improvement yet, so it is incomparable researc

Degussa P-25 nano powders are used to produce slurries. Ethyl cellulose and Alpha-Terpineolare are used as viscous agent and dispersant, respectively. 　　Various additives are used to improve the photoelectric effect of the dye-sensitized solar cells. Furthermore, different process parameters are studied, including increasing the thickness of TiO2, adding a compact layer, treatment of titanium tetrachloride (TiCl4), and adding

Graphene is a potential material for many applications due to their high electron mobility, outstanding optical properties, and thermal, chemical, and mechanical stability. Therefore, this study changes several parameters, structures, and methods to optimize and compare with the traditional DSSCs . There are three major respects about with or without graphene, (1) the method of plating or sputtering,

碩士<br>國立中興大學<br>機械工程學系所<br>102<br>Previous studies had proposed systematic structures for tandem luminescent solar concentrators (LSCs). However, as the use of two or more waveguide plates in combination with dyes is required, they are different from typical LSCs that put a single kind of dye over a single-layered waveguide. In order to simplify the tandem LSCs to be the single-layered configuration, this study proposed the color mixing from two of the three dyes in colors of red, orange, and green to make the mixing dyes of red-orange, orange-green, and red-green colors. They were then coated

Meinong has shown diligent hard work continuously under the watchful eyes of the media. It is a place famous for its Hakkanese Blue Shirts which have a very strong connection to Meinong. Hakkanese Blue Shirts symbolize a place such as Meinong. In the past, there were not many people discussing this relationship to the Blue Shirts, Hakkanese had forgotten the connection as well. They all remembered wearing Blue Shirts but they had not made the connection to the once flou
