    • Printing of conductive layers on and/or in semiconductor materials using acoustic focusing to create a standing half-wave sound wave across a capillary. In response to the acoustic pressure, particles denser than the fluid in the capillary are driven to the node in the center of the capillary to concentrate metal particles within an organic solvent flowing through the capillary. Depositing the focused flow on a surface and/or substrate creates a line of metal particles that can be subsequently treated to create a conductive line. The concentrated metal particles are arranged in a stream of ink and subsequently deposited on a surface, creating a long pile of metal particles that are subsequently treated to form a conductive line for use in photovoltaic arrays.
    • 使用声聚焦在半导体材料上和/或半导体材料上印刷导电层,以在毛细管上产生静止的半波声波。 响应于声学压力,比毛细管中的流体更致密的颗粒被驱动到毛细管中心的节点,以将金属颗粒集中在流过毛细管的有机溶剂中。 将聚焦的流体沉积在表面和/或基底上产生一系列金属颗粒,其可以随后被处理以产生导电线。 浓缩的金属颗粒被布置成墨水流并随后沉积在表面上,产生长的金属颗粒,随后被处理以形成用于光伏阵列的导线。
