Abstract
Reflektive Beschichtungen auf Glas- und Polymersubstraten als Bestandteile von Solarmodulen, gekennzeichnet dadurch, daß die Beschichtungen je nach Anwendungsfall auf der der Solarstrahlung zugewandten Oberfläche der Solar- Frontgläser oder auf ihrer Rückseite aufgebracht sind und auf den Modulen einen ausreichenden Kühlungseffekt hervorrufen ohne wesentliche Einbußen ihrer elektrischen Leistung und das Licht in den gewünschten PAR -Bereich gleichmäßig unter die Module verteilen.Reflective coatings on glass and polymer substrates as components of solar modules, characterized in that the coatings are applied depending on the application on the solar radiation-facing surface of the solar front glass or on its back and cause a sufficient cooling effect on the modules without significant loss of their electrical Distribute power and light evenly among the modules in the desired PAR area.
Description
Die Erfindung betrifft reflektive Beschichtungen auf Glas - und Polymersubstraten, die auf dem Gebiet der Solartechnik effektive Anwendungen finden.The invention relates to reflective coatings on glass and polymer substrates which have effective applications in the field of solar technology.
Eine große Bedeutung erlangten kühlende Schichten (super weiß), die mehr als 95 % der Solarstrahlung reflektieren und dadurch einen Kühleffekt zwischen 5 K und 10 K gegenüber ihrer Umgebung hervorrufen (Strahlungskühlung ). Durch diesen Effekt können z.B. Dächer und Häuserfronten abgekühlt werden und bei der Klimatisierung von Gebäuden bedeutende Energiemengen eingespart werden. Die betreffenden reflektierenden Beschichtungen reflektieren insbesondere die Solarstrahlung im NIR-Bereich (nahen infraroten Spektralbereich, ) sehr effizient und emittieren die Strahlung durch das atmosphärische Fenster (zwischen 8 und 13µm ) bis in das Weltall und vermindern dadurch die Erderwärmung (
Ausführungsbeispieleexemplary embodiments
1. Zur Strahlungskühlung stromliefernder Überdachungen für Terrassen, Gewächshäuser, Parkplätze etc. werden zunächst Solarfrontgläser auf der der Solarstrahlung zugewandten Oberfläche mit einem Reflektorlack auf Basis von Iriotec 9875-oder 9872-Pigmenten beschichtet. Die mit dem Reflektorlack beschichteten Solarfrontgläser werden dann nach bekannten Technologien mit monokristallinen Siliziumzellen zu Solarmodulen verarbeitet. Zur Strahlungskühlung werden die mit den Reflektorlacken beschichteten Module als Terrassenüberdachung verwendet. Gegenüber unbeschichteten Modulüberdachungen wird bei starker Sonneneinstrahlung die Temperatur unter den Modulen beispielseise von 38°C auf 33°C gesenkt. Die erfindungsgemäßen Reflektorlacke können auch auf Solarmodulen bei der Kühlung von Gewächshäusern oder auch von Häuserfassaden oder bei der AGRI-PV sehr vorteilhaft angewendet werden.1. For radiation cooling of electricity-supplying roofing for patios, greenhouses, parking lots, etc., the surface of the solar front glass facing the solar radiation is first coated with a reflector paint based on Iriotec 9875 or 9872 pigments. The solar front glasses coated with the reflector paint are then processed into solar modules using known technologies with monocrystalline silicon cells. The modules coated with the reflector paint are used as terrace roofs for radiation cooling. Compared to uncoated Module roofing reduces the temperature under the modules, for example, from 38°C to 33°C in strong sunlight. The reflector coatings according to the invention can also be used very advantageously on solar modules for cooling greenhouses or house facades or for AGRI-PV.
2. Die auf einer Vorratsrolle befindliche EVA- Folie der Dicke von 250 µm wird über Transportrollen in eine Lack-Sprühzone geführt, in der der erforderliche diffus reflektierende Reflektorlack auch als rot fluoreszierender Phosphor mit den gewünschten spektralen Transmissionen, z.B. über Masken strukturiert aufgesprüht wird. Danach gelangt die srukturiert beschichtete Folie über Zugrollen in eine Heizungszone mit Temperaturen von etwa 50°C, wo die Lackschicht getrocknet und das Lösungsmittel ausgetrieben werden. Die Geschwindigkeiten der Transport- und Zugrollen sind so bemessen, daß die zu beschichtende Folie unter Vorspannung steht und beim Beschichten nicht relaxieren kann. Zur strukturierten Beschichtung der EVA- Folien sind auch Drucktechniken, wie z.B. Siebdruck möglich. Die auf diese Weise strukturiert beschichteten EVA-Folien können direkt bei der Herstellung von semitransparenten Solarmodulen effizient angewendet, indem sie auf der Rückseite der betreffenden Solarglassubstrate aufgesiegelt werden. Durch definiertes Design hinsichtlich der Anordnung der Solarzellen und der Beschichtungen und Einstellung der Schichtdicken und Breite der Schichten auf den EVA-Folien lassen sich vorgegebene optische Transmissionen der Module einstellen und eine homogene Lichtverteilung unter den Modulen realisieren.2. The EVA film with a thickness of 250 µm on a supply roll is guided via transport rollers into a paint spray zone, in which the required diffusely reflecting reflector paint is also sprayed on as red fluorescent phosphor with the desired spectral transmissions, e.g. in a structured manner using masks. The foil with the structured coating then reaches a heating zone with temperatures of around 50°C via pull rollers, where the paint layer is dried and the solvent is expelled. The speeds of the transport and tension rollers are dimensioned in such a way that the film to be coated is under tension and cannot relax during coating. Printing techniques such as screen printing are also possible for structured coating of the EVA films. The EVA films structured in this way can be efficiently used directly in the manufacture of semi-transparent solar modules by being sealed on the back of the relevant solar glass substrate. A defined design with regard to the arrangement of the solar cells and the coatings and the adjustment of the layer thicknesses and width of the layers on the EVA foils allows the specified optical transmissions of the modules to be set and a homogeneous light distribution among the modules to be achieved.
