My PhD Thesis – Detailed Outline

Chapter 1 of my PhD thesis “Organic Solar Panel Architectures” comprises the motivation (limited oil sources, ecological impact of fossil fuel combustion, status of present inorganic solar panel technology) and description from the thesis.

Chapter 2 is aimed introducing researchers who are intending to focus on organic solar panels into this very specialised but additionally interdisciplinary field. The greater general qualities of organic semiconductors are available in many excellent books along with other references and therefore are only summarized briefly in part one whereas the 2nd part provides a more comprehensive understanding of the key characteristic solar panel parameters and links together. Actually, this Chapter includes a unique compilation and review of “organic solar panel relevant understanding” that’s in conjuction with the experience, understanding and examine from the author.

However, since a complete theoretical knowledge of organic solar panels continues to be difficult we’ve attempted to enhance knowledge of device physics by drawing analogies to inorganic cells while using equivalent circuit diagram and also the “traditional” interpretation of current current characteristics.

The following Chapters cope with the 4 known device architectures: the only layer (Chapter 3 ), double layer (Chapter 4 ), blend (Chapter 5 ) and also the laminated device (Chapter 6 ).

All of them starts with market research of characteristic parameters of already reported devices – such as the outcomes of this thesis – mentioning specific advantages and experienced problems.

Chapter Seven concerns single layer devices comprising a liquid crystalline semiconductor. The outstanding qualities of discotic liquid crystals justify the discussion of the device inside a Chapter separated in the single layer device Chapter.

Additionally, it comprises market research from the interesting transport (charge carrier mobility) qualities of liquid crystalline semiconductors along with the mesogenic portrayal of a number of discotic molecules that a person accustomed to fabricate just one layer solar panel.

How solar panel efficiencies can be established inside a reasonable yet practical way either by establishing a solar simulator or statistical simulation is discussed in Chapter 8.

Chapter 9 concludes with a listing of the characteristic parameters comprising all solar panel architecture, a general assessment, a few recommendations for future investigations along with a comprehensive bibliography.

Information on sample preparation and measurements in addition to a listing of publications through the author along with a brief CV are available in the Appendices in Chapter 10.

The item of the thesis was the analysis of various organic semiconductors (preferably with low bandgaps) in numerous solar panel architectures. However, the next findings might be of particular interest for experts and newcomers within the field:

We’ve introduced a brand new device architecture that mixes benefits of double layer and blend devices and opens exciting new options in device design for example selective doping. Two laminated products are discussed in Chapter 6.

We’ve proven the very first time that dye/dye interfaces can be used as photogeneration of charges in solar panels.

In Chapter Seven we’ve proven that dyes with liquid crystalline qualities can be used active semiconducting components in solar panels. Our results along with the recent literature indicate that heating in to the liquid crystalline phase is not required.

All devices discussed within the Chapters on double layer, blends and laminated structures show spectral responses covering a minimum of the wave length selection of visible light. Two devices even were built with a obvious photo-response lower to some wave length of 1000nm.

The only layer device comprising PTV shows a really strong monoton dependency from the EQE around the wave length so the device can be used simple colour – or perhaps – wave length detector since the entire visible range.

We’ve studied results of film thickness and also have discovered that individuals devices which have the thinnest films (10-30nm, that is close to the believed exciton diffusion length) provide the greatest currents. A means to estimate the perfect thickness continues to be introduced. However, we’ve also discovered that the shunt resistor grows 30 to 100 occasions quicker than the series resistor with growing film thickness favouring thicker films for bigger fill factors.

In Chapter 8 we describe the way the standard solar spectrum could be simulated having a easy setup that may be built-in most laboratories for a small fraction of the price of commercial simulators. We discuss a technique exclusively according to intensity dependent photocurrent/current measurements you can use to estimate the AM1.5 efficiency of solar panels.

Note. The word “we” can be used through the text within the thesis to underline the truth that each and every consequence of the author’s act as symbolized within this thesis was just possible due to the provision of equippment, materials and scientific input from others. This is reflected within the lengthy list of subscribers pointed out within the acknowledgment and in conjuction with the proven fact that modern research depends on collaboration and working together.
