Description
Hintergrund der ErfindungBackground of the invention
1. Erfindungsfeld1. field of invention
Die vorliegende Erfindung betrifft allgemein Solarzellen und insbesondere, aber nicht ausschließlich Verfahren und Werkzeuge zum Herstellen von Solarzellen.The present invention relates generally to solar cells, and more particularly but not exclusively to methods and tools for making solar cells.
2. Stand der Technik2. State of the art
Solarzellen sind bekannte Einrichtungen zum Wandeln von Sonnenstrahlen zu elektrischer Energie. Solarzellen können auf einem Halbleiterwafer unter Verwendung einer Halbleiter-Verarbeitungstechnik hergestellt werden. Eine Solarzelle umfasst Diffusionsbereiche des P-Typs und des N-Typs. Eine auf die Solarzelle einfallende Sonnenstrahlung erzeugt Elektroden und Löcher, die zu den Diffusionsbereichen wandern und Spannungsdifferentiale zwischen den Diffusionsbereichen erzeugen. In einer Solarzelle mit rückseitigen Kontakten befinden sich die Diffusionsbereiche und die damit verbundenen Metallkontaktfinger auf der Rückseite der Solarzelle. Die Kontaktfinger ermöglichen, dass ein externer Stromkreis mit der Solarzelle verbunden und durch dieselbe mit Strom versorgt wird.Solar cells are known devices for converting solar radiation into electrical energy. Solar cells can be fabricated on a semiconductor wafer using a semiconductor processing technique. A solar cell includes P-type and N-type diffusion regions. Solar radiation incident on the solar cell produces electrodes and holes which migrate to the diffusion regions and create voltage differentials between the diffusion regions. In a solar cell with back-side contacts, the diffusion regions and the associated metal contact fingers are on the back of the solar cell. The contact fingers allow an external circuit to be connected to and powered by the solar cell.
Eine Kante der Solarzelle kann mit einem Dielektrikum beschichtet werden, um eine elektrische Isolation vorzusehen und ein Ablagern oder Wachsen von Metall an dem Substratumfang zu verhindern. Die vorliegende Erfindung betrifft Vorrichtungen und Verfahren zum Beschichten von Kanten von Solarzellen-Substraten für die Massenproduktion.An edge of the solar cell may be coated with a dielectric to provide electrical isolation and prevent deposition or growth of metal on the substrate periphery. The present invention relates to apparatus and methods for coating edges of solar cell substrates for mass production.
ZusammenfassungSummary
Eine Kantenbeschichtungsvorrichtung ist kofiguriert, um ein Beschichtungsmaterial auf eine Kante eines nicht-kreisförmigen Solarzellensubstrats aufzutragen. Das Substrat wird auf einer drehbaren Substrathalterung angebracht, die die Form eines zum Halten und Drehen des Substrats konfigurierten Futters aufweist. Ein Beschichtungsmaterialspender umfasst eine Auftrageeinrichtung in der Form einer Rolle, die einen rillenförmigen Vertiefungsteil aufweist. Während der Kantenbeschichtung wird die Rolle derart positioniert, dass die Kante des Substrats in der Rille aufgenommen wird. Eine gerändelte Fläche des Rolle kontaktiert die Kante des Substrats, um ein Beschichtungsmaterial auf die Kante des Substrats aufzutragen. Ein Motor dreht das Futter über einen Riemen und eine Welle, um das Substrat für die Kantenbeschichtung zu drehen.An edge coater is configured to apply a coating material to an edge of a non-circular solar cell substrate. The substrate is mounted on a rotatable substrate holder which is in the form of a chuck configured to hold and rotate the substrate. A coating material dispenser comprises an applicator in the form of a roller having a groove-shaped recess portion. During edge coating, the roll is positioned so that the edge of the substrate is received in the groove. A knurled surface of the roll contacts the edge of the substrate to apply a coating material to the edge of the substrate. A motor turns the chuck over a belt and a shaft to rotate the substrate for the edge coating.
