Abstract

In a solar energy collector, a photoelectric layer is combined with an energy-absorbing layer so that both electrical and heat energy may be produced simultaneously. The collector incorporates a photoelectric layer in which material such as CdS is vapour-deposited in a plastic film; the latter serves to seal the complete collector unit and make it weatherproof. Used in solar energy systems for prodn. of electricity and also for the pumping and heating of sea-water used in biological processes. Overall energy recovery efficiency is increased; the heat energy may be utilised in a thermal storage system to allow continuous prodn. of electricity during hours of darkness.

Description

Bivalenter SonnenenergiewandlerBivalent solar energy converter

Die Erfindung bezieht sich auf einen Sonnenenergiewandler zur Erzeugung von Elektrizität. Es ist bekannt, elektrische Energie auf direktem Wege als Fotoelektrik zu erzeugen, wie dies insbesondere in der Raumfahrt Eingang gefunden hat. Daneben sind viele Verfahren und Vorrichtungen bekannt geworden, die auf Niedertemperaturkreisprozessen beruhen und als Wärmequelle den Solarkollektor nutzen. Die Erfindung bezieht sich auf bival Sonnenenergiewandler. Gemäß der Erfindung wird der Kollektor einer Dampfkraftanlage zur Erzeugung von Elektrizität zusätzlich mit einer Schicht versehen, die Fotoströme erzeugt. Vorzugsweise bedient sich die Erfindung dabei eines neuartigen Aufbanes der fotoelektrischen Schicht, indem eine zum Sonnenlicht weisende Folie mit einer leitenden, vorzugsweise als Gitter ausgebildeten Schicht bedampft wird und wobei danach die fotoelektrisch aktive Schicht z.B. Cadmiumsulfid durch Aufdampfung aufgebracht wird, während die dem thermischen Kollektor zugewandte Schicht wiederum als Leitschicht ausgebildet wird und wie die oberste Schicht mit Sammelleitern verbunden wird. Hierdurch ist ein sicherer Schutz gegenüber den Witterungseinflüssen möglich.The invention relates to a solar energy converter for generation of electricity. It is known to generate electrical energy in a direct way as photoelectrics to generate, as this has found its way into space travel in particular. Besides Many methods and devices have become known that rely on low-temperature cycle processes and use the solar collector as a heat source. The invention relates to on bival solar energy converter. According to the invention, the collector of a steam power plant For the generation of electricity additionally provided with a layer, the photocurrents generated. The invention preferably makes use of a novel structure the photoelectric layer by placing a film facing the sunlight with a conductive, preferably formed as a grid layer is vaporized and wherein then the photoelectrically active layer, e.g. cadmium sulfide, is applied by vapor deposition while the layer facing the thermal collector is used as a conductive layer and how the top layer is connected to bus bars. Through this reliable protection against the effects of the weather is possible.

Die theoretisch erzielbaren Wirkungsgrade der Direktumwandlung liegen heute bei etwa 12 %, vom Erfinder wurden 6,5 % bereits gemessen. Damit wird ein erster Anteil der Solaronergie unmit#elbar in Elektrizität umtewandelt. Die verbleibenden rund 90 ~ der Energie dienen zur Aufheizung eines Wärmeträgers für einen geschlossenen thermodynamischen Dampfprozess. Dieser Prozess wird zur Erzeugung von Elektrizität eingesetzt und zusätzlich erfindungsgemäß vorteilhaft zur Aufladung thermischer Speicher verwandt. Hierdurch ist es möglich, unabhängig von der Einstra#ldauer und je nach Speichergröße auch während längerer Bewölkungsperioden kontinuierlich e#lektrische Leistung bereitzustellen, der während der Einstrahlungsstunden, also während der Tagesstunden, an denen ohnehin der Elektrizitätsverbrauch ansteigt, die Leistung der fotoelektríschen Schicht aufgeprägt wird.The theoretically achievable degrees of efficiency of direct conversion are today at around 12%, the inventor has already measured 6.5%. This becomes a first share of solar energy converted directly into electricity. The remaining Around 90 ~ of the energy is used to heat a heat carrier for a closed one thermodynamic steam process. This process is used to generate electricity used and additionally advantageous according to the invention for charging thermal Memory used. This makes it possible, regardless of the duration of exposure and depending on the storage capacity, continuous electrical energy even during longer periods of cloudiness Provide power during the hours of irradiation, i.e. during the Hours of the day when electricity consumption increases anyway, the power the photoelectric layer is impressed.

Erfindungsgemäß wird dabei der Fotostrom in an sich bekannter Weise in die gleiche Stromart verwandelt, wie sie der t-hermadynamische Prozess liefert Die Erfindung kann auch zur gleichzeitigen Bereitstellung von Energie für verschiedene Anwendungsbereiche eingesetzt werden.According to the invention, the photocurrent is used in a manner known per se transformed into the same type of current as the t-hermadynamic process delivers The invention can also be used for the simultaneous provision of energy for different Areas of application are used.

So wurde das erfindungsgemäßePrinzip für den Antrieb von Unterwasserpumpen zur Förderung von nährstoffhaltigem Tiefseewasser eingesetzt, welches zur Intensivierung der biologischen Produktion aufgeheizt und dem Sonnenlicht ausgesetzt wird. Die Aufheizung dieses Tiefenwassers erfolgt dann erfindungsgemäß in der die Wärme bildenden Schicht des bivalenten Solarkollektors. Bei dieser Anwendung fallen Elektrizitätserzeugung und Elektrizitätsbedarf in prozessbedingter Weise zusammen.This is how the principle according to the invention was used for driving submersible pumps Used for the promotion of nutrient-rich deep sea water, which is used for intensification the biological production is heated up and exposed to sunlight. the According to the invention, this deep water is then heated in the area that forms the heat Layer of the bivalent solar collector. In this application, electricity generation is covered and electricity demand together in a process-related manner.
