  • Publication number: 20240429328
    Abstract: A method of deposition on a substrate used for the manufacture of a solar cell is provided. The method includes depositing a first conductive pattern on a first side of the substrate. The first conductive pattern is one of a plurality of busbars and a plurality of fingers. The method includes providing a screen over the substrate. The screen includes a set of openings. The screen has a bottom side having a varying vertical profile including low portions and high portions. The method includes transferring a printing material from the screen to the substrate through the set of openings to print a second conductive pattern on the first side of the substrate. The second conductive pattern is the other one of the plurality of busbars and the plurality of fingers. During the printing of the second conductive pattern, the first conductive pattern is substantially wet and the screen is disposed over the substrate in a manner such that the high portions are elevated above the first conductive pattern.

  • Publication number: 20240416645
    Abstract: A processing line for processing a substrate used for the manufacture of a solar cell is provided. The processing line includes a first station including a first chamber. The processing line includes a second station. The second station includes a second chamber and a printer in the second chamber. The processing line includes a linear guide extending at least from the first chamber to the second chamber. The processing line includes a robot arm. The processing line includes an actuator assembly to move the robot arm along the linear guide. The robot arm is movable along the linear guide to a position inside the first chamber. The robot arm is movable along the linear guide to a position inside the second chamber.

  • Publication number: 20240262118
    Abstract: A method of performing screen printing on a substrate used for the manufacture of a solar cell is provided. The method includes moving a print head over a screen by a first drive actuator to perform a printing stroke in a first direction. The method includes moving a material processing head in the first direction by a second drive actuator to perform a material processing stroke behind the print head. The print head is moved away from the material processing head by the first drive actuator during a distance increasing phase of the printing stroke to increase a separation distance between the print head and the material processing head.

  • Publication number: 20240170604
    Abstract: A method (500) for printing on a substrate (102) for the production of a solar cell, the method comprising: printing (501) a wet pattern on the substrate (102); extracting (503) three-dimensional morphological data of the wet pattern (104?) in real-time using an in-line profilometer (101); wherein the printing of the wet pattern on the substrate is controlled in real time at least in part based on previous three-dimensional morphological data obtained by extracting the three-dimensional morphological data.

  • Patent number: 11958284
    Abstract: A method for screen printing of a material on a substrate is provided. The method includes moving a process head assembly having at least one deposition device from a first position to a second position to perform a stroke, wherein the stroke includes at least a first phase for material processing of a material on a screen device using the at least one deposition device and a second phase for a material transfer from the screen device to the substrate. The at least one deposition device moves in a first direction in the first phase. At least one device moves in a second direction perpendicular to the first direction in the first phase. The at least one deposition device and the at least one device simultaneously move during at least a part of the first phase. The at least one device is selected from the group including the at least one deposition device, a material processing device, the screen device, and a substrate support.

  • Patent number: 7607912
    Abstract: A mould holding cross member (9) according to the invention comprises a support base (91) a suitable to compress the mould (S) and more projecting, in the mould closing direction, than the ends (90) with which the cross member is connected to the moving columns (6) of the press on which it is fitted. The base (91) is connected to the rest of the cross member by a narrow portion (99) which extends in the central area of the base and between the projections of the hinging areas (7, 8) of the double toggle of the press on the press bed (2), and substantially not outside those projections. In this way the pressures are more uniformly distributed on the mould (S). The present invention also concerns a press fitted with a cross member (9) as defined above.
