Wolfgang Pauli 4 Abstract Lead halide perovskites are a class of solution-processable semiconductor materials showing great potential for photovoltaic applications. While perovskite solar cell (PSC) efficiencies have escalated rapidly to beyond 22% in recent years, the materials suffer from a number of chemical instabilities and the processes underlying the optoelectronic response of devices are not well understood. This thesis investigates the device physics of PSCs using novel transient optoelectronic measurements combined with device simulation. A one-dimensional numerical drift-diffusion model capable of solving for electrons, holes and a single ionic charge carrier was developed to simulate perovskite devices. The inclusion of a high density of mobile ionic species in the absorber layer is found to have important consequences on both device performance and the interpretation of established measurements. Transient optoelectronic measurements are presented showing that mobile ions are present in architectures of PSC that do not exhibit current-voltage hysteresis. Simulations of p-i-n structured devices indicate that a combination of mobile ions and field-dependent interfacial recombination rates are critical to reproducing hysteresis. Transient ideality factor measurements are used to identify the dominant recombination mechanisms in PSCs. Changes in the perceived ideality factor are correlated to localised recombination, the charge carrier population overlap, and ion density profiles in simulated devices. Simulations are used to assess the validity of a zero-dimensional model applied to small perturbation transient photovoltage (TPV) measurements on perovskite devices. Two analytical models are proposed to explain the different regimes of behaviour in devices with high rates of interfacial recombination. The TPV decay in perovskites is identified as being predominantly a measure of the transport properties of the absorber layer. Together these findings demonstrate the combined power of experimental measurements and simulation to improve our physical understanding of new semiconductor technologies. 5 6 Acknowledgements For their undying faith in the face of certain failure, I would like to thank the following people: First and foremost my brilliant supervisors Piers and Jenny: thank you for rearing me from an engineering graduate who thought he didn't understand anything to a postgraduate physicist who knows he doesn't understand anything.

However, suc- cessful extraction of photocarriers from perovskites and their conversion to electrical signals remain challenging due to the interdependency of photogain and dark current density.

Ginger Chemistry Solution processable materials present a competitive alternative to traditional silicon solar cells based on inexpensive processing and flexible form factors. Several competing technologies have entered the market in the past few years, including cadmium telluride and copper, indium, gallium, sulfur (CIGS) alloys. In addition to this nascent commercialized product, several emerging technologies also offer promising alternatives. Copper, zinc, tin, sulfur (CZTS) kesterite materials offers an earth abundant option, moving away from more price volatile minerals such as the indium used in CIGS. Hybrid perovskites (HPs) have been revealed as one of the most exciting new solution processable materials, with efficiency improving exponentially in just the past several years.

  • Structure Prediction, Growth, and Characterization of Perovskites
    STRUCTURE PREDICTION, GROWTH, AND CHARACTERIZATION OF PEROVSKITES A Dissertation Presented to the Faculty of the Graduate School of Cornell University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Eva Helena Smith August 2017 c 2017 Eva Helena Smith ALL RIGHTS RESERVED STRUCTURE PREDICTION, GROWTH, AND CHARACTERIZATION OF PEROVSKITES Eva Helena Smith, Ph.D. Cornell University 2017 The heart of materials science is understanding the relationship between structure (how molecules are connected at the atomic level, as well as in hierarchical building blocks) and properties. Historically this has been achieved by studying the properties of materials in hand, either found in nature or synthesized in the laboratory. As the understanding of the relationship between structure and properties has grown, and our ability to calculate and in particular to solve Schrodinger’s¨ equation for solids has improved, so too has our desire and ability to predict structures with enhanced properties through computation. In this thesis I do each of those three tasks – prediction, synthesis, and characterization – on a system that is of interest in its own right and which I hope may yield results that can be applied to other materials systems as well. All of these systems are materials in the highly-versatile perovskite structure, which can accommodate most of the elements of the periodic table. Perovskites have been the object of much study in the laboratory as well as being used extensively in industrial applications, with such properties as ferroelectricity, piezoelectricity, ferromagnetism, and superconductivity. First, I delineate the chemical factors that determine the ground-state structure of CsPbF3.

    Dissertation zur Erlangung des Doktorgrades der Fakultät für Chemie und Pharmazie der Ludwig-Maximilians-Universität München Synthesis and Characterization of Novel Perovskite Materials for Solar Cell Applications Andreas Christian Herbert Binek aus Schwabmünchen, Deutschland 2016 I Erklärung Diese Dissertation wurde im Sinne von § 7 der Promotionsordnung vom 01.April 2014 von Herrn Prof. Dr. Thomas Bein betreut. Eidesstattliche Versicherung Diese Dissertation wurde eigenständig und ohne unerlaubte Hilfe bearbeitet. München, 15.02.2017 Andreas Binek Dissertation eingereicht am 29.12.2016 1. Gutachter: Prof. Dr. Thomas Bein 2. Gutachter: Prof. Dr. Achim Hartschuh Mündliche Prüfung am 10.02.2017 III Preface Danksagung Ich möchte mich zuerst einmal bei meinem Doktorvater Prof. Dr. Thomas Bein für die Aufnahme in seine Gruppe zur Doktorarbeit bedanken. Er gab mir eine Chance, in der physikalischen Chemie Fuß zu fassen, obwohl ich mein Studium eher in der anorganischen Chemie verbracht habe. Jedoch ermutigte er mich stets, mein angesammeltes Wissen in mein neues Forschungsgebiet mit einzubringen, um somit die Brücke zwischen physikalischer und anorganischer Chemie zu schließen. Des Weiteren danke ich Prof. Dr. Achim Hartschuh, der sich bereit erklärt hat, meine Doktorarbeit als zweiter Gutachter zu bewerten. Die Zusammenarbeit mit dem AK Hartschuh war stets sehr produktiv und ermöglichte mir, mit Hilfe von modernen Messmethoden viel über Ladungstransport in Solarzellen zu lernen. Ein großer Dank geht auch an Dr. Pablo Docampo, der mir immer mit Rat und Tat zur Seite stand und sich auch mehrfach Zeit nahm, mir physikalische Zusammenhänge zu erklären. Ohne seine Hilfe wären einige Projekte in eine Sackgasse gelaufen und wären nicht veröffentlicht worden.

  • Oxfordcolleges
    Oxford colleges Oxford University is made up of different colleges. Colleges are academic communities. They are where students usually have their tutorials. Each one has its own dining hall, bar, common room and library, and lots of college groups and societies. If you study here you will be a member of a college, and probably have your tutorials in that college. You will also be a member of the wider University, with access to University and department facilities like laboratories and libraries, as well as hundreds of University groups and societies. You would usually have your lectures and any lab work in your department, with other students from across the University. There is something to be said for an academic atmosphere wherein everyone you meet is both passionate about what they are studying and phenomenally clever to boot.
