Abstract (en)

The device comprises a reservoir (12) having an electrolytic coating liquid (13), a lower transport device (40), and an upper transport device (30) for substrates, where a transport device comprises a unit for contacting and connecting the substrates to a voltage source (21). The upper transport device comprises a tampon (41) of an absorbent material. The unit is provided so that the tampon receives the electrolytic coating liquid and contacts the surface of the substrate to be plated. The transport devices lead the substrates at a distance over a coating pan. The device comprises a reservoir (12) having an electrolytic coating liquid (13), a lower transport device (40), and an upper transport device (30) for substrates, where a transport device comprises a unit for contacting and connecting the substrates to a voltage source (21). The upper transport device comprises a tampon (41) of an absorbent material. The unit is provided so that the tampon receives the electrolytic coating liquid and contacts the surface of the substrate to be plated. The transport devices lead the substrates at a distance over a coating pan. The lower transport device comprises the tampon. The transport devices: comprise a transport roller or transport drum, which is provided with the tampon of the absorbent material or the tampon forms and consists of the absorbent material; and a conveyor belt, which is provided with the absorbent material or the tampon forms and consists of the absorbent material. The conveyor belt is guided in a guide element. A light source for irradiating the surface of the substrates to be coated is arranged in the coating liquid. An independent claim is included for a method for galvanic coating solar cells.

Abstract (de)

Es wird eine Vorrichtung zur galvanischen Beschichtung von Substraten, insbesondere von Solarzellen beschrieben. Die Vorrichtung weist ein Reservoir (12) mit einer elektrolytischen Beschichtungsflüssigkeit (13) sowie eine untere Transporteinrichtung (40) und eine obere Transporteinrichtung (30) für das Substrat (1) auf. Eine Transporteinrichtung weist Mittel (20, 21, 24, 32) zum Kontaktieren und Anschließen des Substrats (1) an eine Spannungsquelle (21) auf. Mindestens eine Transporteinrichtung (30) weist mindestens einen Tampon (41) aus einem saugfähigen Material (44) auf. Ferner sind Mittel vorgesehen, so dass der Tampon (41) elektrolytische Beschichtungsflüssigkeit (13) aufnimmt und die zu galvanisierende Oberfläche des Substrats (1) kontaktiert. Es wird auch ein Verfahren zur galvanischen Beschichtung von Solarzellen beschrieben.
