Design of Transparent Conducting Electrodes and Surface Relief Gratings for Plasmonic Polymer Solar Cells

As the concept of renewable energy becomes increasingly important in the modern society, a considerable amount of research has been conducted in the field of organic photovoltaics in recent years. Although organic solar cells generally have had lower efficiencies compared to silicon solar cells, they have the potential to be mass produced via solution processing. A common polymer solar cell architecture relies on the usage of P3HT (electron donor) and PCBM (electron acceptor) bulk heterojunction. One of the main issues with this configuration is that in order to compensate for the high exciton recombination rate, the photoactive layer is often made very thin (on the order of 100 $%). This results in low solar cell photocurrents due to low absorption. This thesis investigates a novel method of light trapping by coupling surface plasmons at the electrode interface via surface relief gratings, leading to EM field enhancements and increased photo absorption. Experimental work was first conducted on developing and optimizing a transparent electrode of the form &'()/+,/&'() to replace the traditional ITO electrode since the azopolymer gratings cannot withstand the high temperature processing of ITO films. It was determined that given the right thickness profiles and deposition conditions, the MAM stack can achieve transmittance and conductivity similar to ITO films. Experimental work was also conducted on the fabrication and characterization of surface relief gratings, as well as verification of the surface plasmon generation. Surface relief gratings were fabricated easily and accurately via laser interference lithography on photosensitive azopolymer films. Laser diffraction studies confirmed the grating pitch, which is dependent on the incident angle and wavelength of the writing beam. AFM experiments were conducted to determine the surface morphology of the gratings, before and after metallic film deposition. It was concluded that metallic film deposition does not significantly alter the grating morphologies.

Saint-Domingue Refugees and their Enslaved Property : Abolition Societies and the Enforcement of Gradual Emancipation in Pennsylvania and New York

Ce mémoire porte sur le rôle des cercles abolitionnistes dans l’application des lois sur l’émancipation graduelle de l’esclavage dans le nord des États-Unis vers la fin du dix-huitième siècle, principalement à New York et en Pennsylvanie. Plus particulièrement, il met en lumière la façon dont ces cercles, dont les deux plus importants étaient la Pennsylvania Abolition So-ciety (PAS) et le New­York Manumission Society (NYMS), ont fait face aux centaines de réfugiés de Saint-Domingue qui sont arrivés avec leurs esclaves sur la côte est américaine pour fuir la révolution haïtienne dans les années 1790. Dans un premier temps, ce mémoire étudie l’abolition graduelle de l’esclavage dans le nord des États-Unis, débutant avec la Pennsylvanie en 1780, et la formation des cercles abolitionnistes dans les anciennes colonies anglaises. Il sera en outre question des stratégies des antiesclavagistes américains afin de promouvoir l’abolition graduelle de l’esclavage et d’empêcher le mouvement des esclaves et des noirs libres en dehors des frontières de leurs États respectifs. Il sera aussi question de leurs efforts pour resserrer davantage les clauses des lois existantes à ce sujet. Dans un second temps, dans le but de mettre en relief la contribution des cercles abolitionnistes, ce mémoire procède à une étude de cas sur la manière dont les réfugiés de Saint-Domingue ont interagi avec l’esclavage résiduel à New York et en Pennsylvanie et cherche à comprendre pourquoi leurs tentatives d’échapper aux lois sur l’émancipation graduelle se sont heurtées, à plusieurs reprises, aux stratégies des sociétés antiesclavagistes.

Report of the Tax Study Committee to the House of Representatives of the General Assembly of South Carolina.

This is a report by the Committee that was created by House Resolution 1691 of 1965 for the purpose of studying the State's tax laws relating to the assessment and collection of ad valorem taxes by the political subdivisions of the state. The Committee found that some statutory requirements relating to reporting and assessment of property for local tax purposes were being ignored for practical reasons, and that, in the opinion of the Committee, actual practice was sometimes productive of better results than existing legal requirements. In those cases, the Committee has recommended changes in the law so that legal requirements will coincide with desirable practice.

Property cash flow studies : focusing on model consistency and data accuracy

The high degree of variability and inconsistency in cash flow study usage by property professionals demands improvement in knowledge and processes. Until recently limited research was being undertaken on the use of cash flow studies in property valuations but the growing acceptance of this approach for major investment valuations has resulted in renewed interest in this topic. Studies on valuation variations identify data accuracy, model consistency and bias as major concerns. In cash flow studies there are practical problems with the input data and the consistency of the models. This study will refer to the recent literature and identify the major factors in model inconsistency and data selection. A detailed case study will be used to examine the effects of changes in structure and inputs. The key variable inputs will be identified and proposals developed to improve the selection process for these key variables. The variables will be selected with the aid of sensitivity studies and alternative ways of quantifying the key variables explained. The paper recommends, with reservations, the use of probability profiles of the variables and the incorporation of this data in simulation exercises. The use of Monte Carlo simulation is demonstrated and the factors influencing the structure of the probability distributions of the key variables are outline. This study relates to ongoing research into functional performance of commercial property within an Australian Cooperative Research Centre.

The future of office property

The following paper considers the question, where to office property? In doing so, it focuses, in the first instance, on identifying and describing a selection of key forces for change present within the contemporary operating environment in which office property functions. Given the increasingly complex, dynamic and multi-faceted character of this environment, the paper seeks to identify only the primary forces for change, within the context of the future of office property. These core drivers of change have, for the purposes of this discussion, been characterised as including a range of economic, demographic and socio-cultural factors, together with developments in information and communication technology. Having established this foundation, the paper proceeds to consider the manner in which these forces may, in the future, be manifested within the office property market. Comment is offered regarding the potential future implications of these forces for change together with their likely influence on the nature and management of the physical asset itself. Whilst no explicit time horizon has been envisioned in the preparation of this paper particular attention has been accorded short to medium term trends, that is, those likely to emerge in the office property marketplace over the coming two decades. Further, the paper considers the question posed, in respect of the future of office property, in the context of developed western nations. The degree of commonality seen in these mature markets is such that generalisations may more appropriately and robustly be applied. Whilst some of the comments offered with respect to the target market may find application in other arenas, it is beyond the scope of this paper to explicitly consider highly heterogeneous markets. Given also the wide scope of this paper key drivers for change and their likely implications for the commercial office property market are identified at a global level (within the above established parameters). Accordingly, the focus is necessarily such that it serves to reflect overarching directions at a universal level (with the effect being that direct applicability to individual markets - when viewed in isolation on a geographic or property type specific basis – may not be fitting in all instances)
