Abstract: A printing device for dispending material on a heated substrate is provided. The device may include a printing head having one or more nozzles and a heat shield that partially masks a side of the printing head that faces the heated substrate when printing so as to reduce heat transfer from the substrate to the printing head. The shield includes a slot aligned with the one or more nozzles to enable passage of material from the one or more nozzles to the heated substrate.

Abstract: Some aspects of the invention are related to a solar cell, for producing electricity from solar radiation. The solar cell may include a substrate, for example, polycrystalline silicon and an electrically conductive structure disposed on the substrate. The electrically conductive structure may include a bus bar and one or more finger electrodes positioned such that at least a portion of a finger electrode overlaps the bus bar.

Abstract: A printing head assembly with integrated purge mechanism is disclosed. The printing head assembly comprises: (a) a liquid dispensing head comprising one or more dispensing nozzles enclosed in a nozzle plate, driven by at least first and second pressures, and (b) a shielding mask including an opening in front of the one or more nozzles, wherein the opening being configured such that when printing liquid is dispensed from the head driven by the first pressure, the liquid being dispensed in pulses through the opening in the shielding mask, and (ii) when purge printing liquid is dispensed from the head driven by the second pressure, the liquid being drawn to a capillary gap formed between the shielding mask and the nozzle plate thereby removing the purge printing liquid from the nearby nozzles.

Abstract: A method for evaluating performance of a plurality of nozzles of a printing head includes repeatedly operating each of the nozzles to print test marks on a surface of a substrate, each of the test marks printed by that nozzle being printed at a different time. At least once during the repeated operation of each of the nozzles, at least some of the test marks are erased from the surface. The test marks that were printed by that nozzle are inspected for a feature that is indicative of the performance of that nozzle.
