Description

Umfeld der ErfindungEnvironment of the invention

Diese Erfindung gehört zur Photovoltaik und dient der Erzeugung elektrischer Energie durch Licht.This invention belongs to photovoltaics and serves to generate electrical energy by light.

Hintergrund der ErfindungBackground of the invention

Solarmodule dienen der Erzeugung elektrischer Energie durch Lichteinfall auf Solarzellen, die als Bestandteile eines Solarmoduls z. B. als Dünnschicht auf eine Glas- oder transparente Kunststoffplatte aufgetragen und in Reihe geschaltet sind. Solarmodule werden üblicherweise so positioniert, dass die lichtempfindlichen Seiten der Solarzellen frontal dem einfallenden Licht ausgesetzt sind, das durch die Glas- oder Kunststoffplatte hindurch gelangt. Der Nachteil der Solarmodule bisheriger Bauart ist, dass sie viel Platz benötigen. Meiner Erfindung liegt die Entdeckung zugrunde, dass durch Beschichtung des Solarmoduls mit einer lichtreflektierenden Farbe, Folie oder Metallschicht bis auf eine frei bleibende, schmale Fläche der die Solarzellen bedeckenden Glas- oder Kunststoffplatte und der angrenzenden Dünnschicht kein wesentlicher Energieverlust durch verminderte Lichteinstrahlung eintritt. Dabei wird die unbedeckte, schmale Fläche der Glas- oder Kunststoffplatte dem Licht ausgesetzt. Der Vorteil ist, dass das Solarmodul vertikal angeordnet werden kann und nur noch wenig Platz verbraucht. Zusätzlich ist das gesamte Modul – bis auf die nicht beschichtete Fläche – durch die reflektierende Schicht gegen Umwelteinflüsse geschützt. Möglicherweise tritt das sogenannte Hot-Spot Problem bisheriger Solarmodule weniger auf, da z. B. ein herabfallendes Blatt nicht direkt einen Bereich der Solarzellen bedecken kann.Solar modules are used to generate electrical energy by incident light on solar cells, which are used as components of a solar module z. B. are applied as a thin layer on a glass or transparent plastic plate and connected in series. Solar modules are usually positioned so that the photosensitive sides of the solar cells are exposed frontally to the incident light that passes through the glass or plastic plate. The disadvantage of the previous modules solar modules is that they need a lot of space. My invention is based on the discovery that by coating the solar module with a light-reflecting paint, foil or metal layer except for a free, narrow surface of the solar cells covering glass or plastic plate and the adjacent thin layer no significant energy loss due to reduced light. The uncovered, narrow surface of the glass or plastic plate is exposed to the light. The advantage is that the solar module can be arranged vertically and uses only little space. In addition, the entire module - except for the uncoated surface - protected by the reflective layer against environmental influences. Perhaps the so-called hot-spot problem of previous solar modules occurs less, since z. B. a falling leaf can not directly cover a range of solar cells.

Details zur ErfindungDetails of the invention

1 zeigt die Erfindung von der Frontseite aus. Das Solarmodul, bestehend aus einer Glas- oder Kunststoffplatte 1, darauf aufgebrachten Dünnschicht aus in Reihe geschalteten Solarzellen 2, Kontakten 3 und 4 zur Abnahme elektrischer Energie sowie einer lichtreflektierenden, das ganze Solarmodul bis auf die in der Frontansicht zu sehenden schmalen Flächen der Platte 1 und der Dünnschicht 2 bedeckenden Schicht 5, 6, 7 und 8. Lichteinfall ist daher nur durch ein schmales Fenster, einer schmalen Fläche der Platte 1 möglich, die in 1 von vorne zu sehen ist. Es ist leicht möglich, ein Standard-Dünnschichtmodul im Sinne meiner Erfindung nachzurüsten. Dazu müssen nur alle Flächen des Moduls bis auf eine schmale Fläche der Platte 1 und der angrenzenden Dünnschicht 2 mit einer lichtreflektierenden Schicht versehen werden. Dann wird das Solarmodul vertikal statt wie bisher horizontal aufgestellt. Denkbar wäre es auch, mehrere Module zu einem Block zusammenzufassen, um mehr Energie zu gewinnen. 1 shows the invention from the front. The solar module, consisting of a glass or plastic plate 1 , applied thereon thin film of series-connected solar cells 2 , Contacts 3 and 4 for the acceptance of electrical energy as well as a light-reflecting, the whole solar module except for in the front view to see narrow surfaces of the plate 1 and the thin film 2 covering layer 5 . 6 . 7 and 8th , Light is therefore only through a narrow window, a narrow surface of the plate 1 possible in 1 can be seen from the front. It is easily possible to retrofit a standard thin-film module in the sense of my invention. All that is required is for all the surfaces of the module to be limited to a small area of the plate 1 and the adjacent thin film 2 be provided with a light-reflecting layer. Then the solar module is placed vertically instead of horizontally as before. It would also be conceivable to combine several modules into one block in order to gain more energy.

2 zeigt die Erfindung in einer Seitenansicht. Zu sehen ist die Glas- oder Kunststoffplatte 1, bedeckt mit lichtreflektierender Schicht 5, 6, 7 und 9. Die einzigen nicht bedeckten Flächen sind eine schmale Seitenfläche der Platte 1 sowie der Dünnschicht 2, von denen in 2 nur eine Kante zu sehen ist. 2 shows the invention in a side view. You can see the glass or plastic plate 1 , covered with light-reflecting layer 5 . 6 . 7 and 9 , The only uncovered surfaces are a narrow side surface of the plate 1 as well as the thin film 2 of which in 2 only one edge is visible.
