Solar cell phd thesis

solar cell, their e ciency at producing electricity from sunlight is characterized by three parameters: their short-circuit current (J sc), open-circuit voltage (V oc) and ll factor (FF). While the factors that determine each of these parameters are well-understood for established solar technologies, this is not the case for organic solar cells PhD Thesis Numerical Analysis for Efficiency Enhancement of Thin Film Solar Cells solar cell performance and how it can be governed.

My PhD Thesis - Detailed Outline Chapter 1 of my PhD thesis "Organic Solar Cell Architectures" comprises the motivation limited oil resources, environmental impact of fossil fuel combustion, status of present inorganic solar cell technology and outline of the thesis.

Chapter 2 is aimed to introduce researchers who are planning to work on organic solar cells into this very specialised but also interdisciplinary field. The more general properties of organic semiconductors can be found in many excellent text books and other references and are only summarized briefly in the first part whereas the second part gives a more comprehensive insight into the important characteristic solar cell parameters and links between them.

In fact, this Chapter contains a unique compilation and summary of "organic solar cell solar cell phd thesis knowledge" that is consistent with the experience, understanding and view of the author. The subsequent Chapters deal with the four known device architectures: the single layer Chapter 3double layer Chapter 4blend Chapter 5 and the laminated device Solar cell phd thesis 6.

Each of them begins with a survey of characteristic parameters of already reported devices - including the results of this thesis - pointing out specific advantages and encountered problems. Chapter 7 concerns single layer devices comprising a liquid crystalline semiconductor, solar cell phd thesis. The outstanding properties of discotic liquid crystals justify the discussion of this device in a Chapter separated from the single layer device Chapter.

It also comprises a survey of the interesting transport charge carrier mobility properties of liquid crystalline semiconductors as well as the mesogenic characterization of a series of discotic molecules from which one has been used to fabricate a single layer solar cell. How solar cell efficiencies can be determined in a reasonable yet practical way either by setting up a solar simulator or numerical simulation is discussed in Chapter 8.

Chapter 9 concludes with a summary of the characteristic parameters comprising all four solar cell architecture, an overall assessment, some suggestions for future investigations and a comprehensive bibliography.

Details of sample preparation and measurements as well as a list of publications by the author and a brief CV can be found in the Appendices in Chapter The object of this thesis was the investigation of various types of organic semiconductors preferably with low bandgaps in different solar cell architectures. However, the following findings may be of particular interest for both experts and newcomers in the field: We have introduced a new device architecture that combines advantages of double layer and blend devices and opens exciting new possibilities in device design such as selective doping, solar cell phd thesis.

Two laminated devices are discussed in Chapter 6. In Chapter 7 we have shown that dyes with liquid crystalline properties can be used as active semiconducting components in solar cells. Our results together with the recent literature indicate that heating into the liquid crystalline phase is not necessary. All devices discussed in the Chapters on double layer, blends and laminated structures show spectral responses covering at least the wavelength range of visible solar cell phd thesis. Two devices even had a clear photo-response down to a wavelength of nm.

The single layer device comprising PTV shows a very strong monoton dependency of the EQE on the wavelength so that the device can be used as simple colour - or even - wavelength detector covering the entire visible range. We have studied effects of film thickness and have found that those devices that have the thinnest films nm, which is near the estimated exciton diffusion length give the highest currents.

A method to estimate the optimal thickness has been introduced. However, we have also found that the shunt resistor grows 30 to times faster than the series resistor with increasing film thickness favouring thicker films for larger fill factors. In Chapter 8 we solar cell phd thesis how the standard solar spectrum can be simulated with a relatively simple setup that can be built in most laboratories for a fraction of the cost of commercial simulators.

Note : The term "we" is used throughout the text in the thesis to underline the fact that every single result of the author's work as represented in this thesis was only possible because of the provision of equippment, materials and scientific input from others.

This is also reflected in the long list of people mentioned in the acknowledgment and consistent solar cell phd thesis the fact that modern research relies on collaboration and teamwork, solar cell phd thesis. Download thesis here Webdesign by K, solar cell phd thesis.
