Electrical Material Properties and Efficiency Limits of Compensated and Multicrystalline Silicon for Solar Cells
Produktform: Buch / Einband - flex.(Paperback)
Increasing the efficiency and reducing the production costs are the two main goals of the optimization of crystalline silicon solar cells. This thesis addresses the impact of efficiency-limiting defects in crystalline silicon from cheaper production routes, namely upgraded metallurgical grade silicon and multicrystalline silicon, and presents an approach for the fabrication of high efficiency solar cells on low-cost multicrystalline silicon substrate.

Development and Characterisation of Advanced Materials for Heat Transformation Applications
Produktform: Buch / Einband - flex.(Paperback)
Thermally driven adsorption processes e.g., sorption based dehumidification or adsorption heat pumps offer a huge potential to reduce buildings related emissions of greenhouse gases. Within this thesis, different challenges on a material level were addressed. A strong focus was set on the use of metal-organic frameworks with water or methanol and a water/methanol mixture as working pairs.

Ozonbasierte Reinigungs- und Konditionierungsverfahren für die Herstellung hocheffizienter Silizium Solarzellen
Produktform: Buch / Einband - flex.(Paperback)
In dieser Arbeit wurden für die Herstellung hocheffizienter Solarzellen ozonbasierte Reinigungs- und Konditionierungsmethoden entwickelt. Diese sind geeignet im industriellen Maßstab Silizium-Wafer von Kontaminationen zu reinigen und die Eigenschaften der Ober- und Grenzfläche, anwendungsspezifisch auf die verwendete Passivierschicht angepasst, vorzubereiten. Der Fokus lag auf der Herstellung und Charakterisierung von ultra-dünnen SiOx-Schichten für das TOPCon Zellkonzept.

Simulation and Characterization of Novel Large-Area Silicon Solar Cells for Industrial Production
Produktform: Buch / Einband - flex.(Paperback)
Novel concepts for crystalline silicon solar cells promise higher energy conversion efficiencies. In order to take one more step towards fulfilling this promise, the present dissertation focuses on new and adapted methods for the inline-characterization, and on optical and electrical simulations of these devices. Three novel concepts are covered: the passivated emitter and rear cell, the selective emitter and the metal wrap through concept.

Quality Rating of Silicon Wafers - A Pattern Recognition Approach
Produktform: Buch / Einband - flex.(Paperback)
The quality of silicon wafers has a strong impact on the efficiency of silicon solar cells. Two critical material characteristics are crystallization related defects and micro-cracks. The detection, quantification and rating of both types of defects in photoluminescence images by means of pattern recognition techniques are in the foci of this work. Let’s see how precise we can rate the quality of an as-cut wafer!
