Abstract: 
Ziel dieser Arbeit ist die Beurteilung von aktiv gekühlten, konzentrierenden Photovoltaik-Receivern in Bezug auf Netzparität und Erzeugerstrompreise unter der Annahme einer maximalen elektrischen Energieproduktion bei ungenutzter Abwärme. Das Verbesserungspotential, sowie eine detaillierte Analyse der theoretischen Grenzen dieser Verbesserungen wird untersucht. Diese Arbeit bietet einen einzigartigen Rahmen für das Verständnis und den Vergleich der Wärmeübertragungseigenschaften und der Leistungsfähigkeit von verschiedenen konzentrierenden Photovoltaik-Receiver Designs.

The purpose of this thesis is to assess whether or not an actively cooled, low concentration, concentrator photovoltaic receiver could meet either grid parity or wholesale electricity prices under the assumption that electrical energy production is maximized and heat is considered a waste load. To do so, a set of cost targets are derived for an actively-cooled concentrator photovoltaic receiver and cooler technology to meet short-term (grid parity) and long-term (wholesale) electricity price targets. The current cost of the receiver and proposed cooler are compared to these targets for three application scenarios, and necessary levels of performance and cost improvements are identified. A list of possible improvements is given, followed by a detailed analysis regarding the theoretical limits of these improvements. Taking these improvements into consideration, a final assessment of the technology is given. Perhaps most importantly, this thesis establishes a detailed and unique framework for understanding and comparing the heat transfer capabilities and ultimately performance of concentrator photovoltaic receiver designs.
