Über dieses Buch

This book addresses electronics and the rise of photonics, and asks what the future holds in store for this technology. It highlights the latest research on all types of solar cells and photonic devices, and a new approach combining photonics and electronics. Beyond simply explaining the existing systems or providing a synthesis of the current state of knowledge, the book also offers readers new perspectives for their own research. Lastly, drawing on the interconnections between electronics and photonics, the book suggests a possible means of using solar energy directly with the aid of future photonic devices.



Chapter 1. A Parallel Between Electronics and Photonics

Analysing the basic materials and continuing with the information carrier vectors, the carriers transport ways, the generators, etc., these two sciences “Electronics” and “Photonics” have a lot of elements in common.

Chapter 2. Theoretical Aspects of Materials Physics

The properties of solids materials, especially the electrons dynamics are determined by the characteristics of the crystalline lattice.

Chapter 3. New Trends in Solar Cells Research

Solar cells converts the solar photons energy into electrical energy. The first solar cell was realized in 1954 at Bell Laboratories. The functioning principles of this first generation solar cells are based on a p-n homojunction realized in a bulk semiconductor (Silicon or GaAs). Figure 3.1 depicts the charge carriers’ distribution and band diagram levels before and after junction formation.

Chapter 4. Trends in Photonics

The name “Photonics” derived from the Greek word “photos” meaning “light” and photonics is closely related to “optics” as the “science of light” in the classical way as a wave (classical optics) and in the quantum way as a particle (quantum optics). With the development of lasers and data transmission, the term of “Photonics” was introduced from the necessity to describe a research field, whose aim was to use light to perform functions that usually fell within the domain of electronics such as information processing. Hence, Photonics can be defined as the science referring to generation, transmission, amplification, detection, modulation and manipulation of photons.

Chapter 5. Energy Conversion or Direct Use?

After discussing about data transmission, materials, transport phenomena in solid state materials, solar energy conversion into electricity and photonic devices, this last chapter is devoted to the Energy.

Unsicherheitsabschätzung für die Berechnung von dynamischen Überschwemmungskarten – Fallstudie Kulmbach

Das vom BMBF geförderte Projekt FloodEvac hat zum Ziel, im Hochwasserfall räumliche und zeitliche Informationen der Hochwassergefährdung bereitzustellen. Im hier vorgestellten Teilprojekt werden Überschwemmungskarten zu Wassertiefen und Fließgeschwindigkeiten unter Angabe der Modellunsicherheiten berechnet.
