Abstract
Der Wirkungsgrad von photovoltaischen Zellen verläuft umgekehrt proportional zur Zellentemperatur. Bei konzentrierenden Solargeneratoren entstehen hohe Temperatursprünge. Gleichzeitig erhöht sich der Ohm'sche Verlust in den Zellen, was zur weiteren Verringerung des Wirkungsgrades führt. Die Erfindung zeigt, wie diese Wärmeströme bei geringstem Temperatursprung abgeleitet werden können.The efficiency of photovoltaic cells is inversely proportional to the cell temperature. Concentrating solar generators cause high temperature jumps. At the same time, the ohmic loss in the cells increases, which leads to further reduction of the efficiency. The invention shows how these heat flows can be dissipated at the slightest temperature jump.
Description
Die Erfindung betrifft photovoltaische Energiewandler, die bei Konzentrator-Generatoren für Solarenergie einen höheren Wirkungsgrad versprechen als bekannte Energiewandler. Bei allen bekannten Systemen führt die Verlustwärmefortleitung zu grossen leistungsverschlechternden Temperaturzunahmen für die energiewandelnden Photozellen, die ausserdem durch die Ohm'schen Verluste in der maximale Bestrahlungsdichte begrenzt sind.The The invention relates to photovoltaic energy converters used in concentrator generators for solar energy a higher one Efficiency promise as known energy converters. At all leads known systems the loss heat transfer to large power-degrading temperature increases for the energy-converting Photocells, in addition, by the ohmic losses in the maximum irradiance are limited.
Die Erfindung besteht aus einer Wärmesenke, die nur aus zwei wärmeleitende Elementen, dem Gehäuse mit extrem kurzen Wärmeleitwegen und aus einer Elektrizitätsbarriere besteht, die einen extrem geringen Wärmewiderstand bietet, wie in Anspruch 1 definiert.The Invention consists of a heat sink, the only two heat-conducting Elements, the housing with extremely short heat conduction paths and from an electricity barrier exists, which offers an extremely low thermal resistance, as in Claim 1 defined.
Zur Verringerung der Ohm'schen Verluste innerhalb der Photozelle weist die Erfindung einen Weg durch Einfügung eines weiteren Leiters, der zwischen den ausleitenden Leitern angeordnet ist, durch den die Ohm'schen Verluste halbiert werden.to Reduction of Ohm's Losses within the photocell, the invention shows a way by insertion another conductor, which is arranged between the diverting conductors is through which the ohms Losses are halved.
Die Erfindung weist also einen Weg zur Verringerung der bisher unvermeidbaren temperaturbedingten Verluste auf.The So invention has a way to reduce the previously unavoidable temperature-related losses.
Die Erfindung soll anhand von Figuren beschrieben werden:The The invention will be described with reference to figures:
