Abstract: Pattern transfer printing (PTP) methods are provided, which comprise: (i) handling a tape with multiple pattern transfer sheets having patterns of trenches, to controllably deliver the pattern transfer sheets for paste filling and consecutively for pattern transfer, (ii) mixing, continuously and uniformly, at least two types of conductive printing pastes having different particle sizes and/or at least one type of conductive printing paste with a NIR (near infrared) absorbing dye—to form a uniform paste mixture, (iii) filling the trenches on the delivered pattern transfer sheets with the paste mixture, (iv) controllably delivering wafers for the pattern transfer, and (v) transferring the paste mixture from the pattern transfer sheets onto the delivered wafers, by releasing the paste mixture from the trenches upon illumination by a laser beam. The methods yield highly accurate, ultrafine conductive lines, e.g., for photovoltaic (PV) applications.

Abstract: The invention provides a novel conductive film and a multilayered conductive structure, comprising a plurality of metal nanowires arranged in clusters and having an average aspect ratio of least 100,000, optionally decorated by metal nanoparticles. It is also disclosed a process for preparation of a conductive film comprising metal nanowires by surfactant/template assisted method which involves the use of a precursor solution based on surfactant (such as CTAB), metal precursor (such as HAuCl4 and AgNO3) and reducing agent (such as metal borohydride or sodium ascorbate).
