Abstract: An apparatus (100) for manufacturing a photovoltaic arrangement is provided. The photovoltaic arrangement includes a conductive tab element (30) and a plurality of overlapping solar cell pieces. The apparatus includes an assembling module (300). The assembling module is configured for assembling a partial photovoltaic arrangement including a first solar cell piece (10a) and the conductive tab element. The assembling of the partial photovoltaic arrangement includes providing the first solar cell piece and the conductive tab element in an overlapping configuration. The assembling module is configured for providing a second solar cell piece (10b) and a solar cell piece of the partial photovoltaic arrangement in an overlapping configuration. The solar cell piece of the partial photovoltaic arrangement may be the first solar cell piece or a third solar cell piece (10c).

Abstract: The present disclosure provides an apparatus for aligning a solar cell element. The apparatus includes a transfer device configured for moving the solar cell element from a first position on a transport device to a second position on a support device, a detection device configured to detect a first orientation of the solar cell element on the transport device and configured to detect a second orientation of the solar cell element held by the transfer device, and a controller configured to change an orientation of the solar cell element held by the transfer device based on at least one of the first orientation and the second orientation to align the solar cell element.

Abstract: The present invention provides a control method and apparatus for printing a multilayer pattern on a substrate. In one embodiment, a method for printing a multilayer pattern includes a first printing operation comprising depositing a first patterned layer on a region of a surface of the substrate, a second printing operation comprising depositing a second patterned layer over the region of the surface or first patterned layer, and verifying the precision of the alignment of the second patterned layer relative to the first patterned layer. Verifying comprises acquiring a first optical image of the first patterned layer after the first printing operation, acquiring a second optical image of the second patterned layer after the second printing operation, and determining the position of the second patterned layer by performing an image subtraction process to form a first subtracted optical image and comparing the subtracted optical image with the first image.
