Abstract: Methods and systems include providing a modular frame having a plurality of frame sections that are connectable to each other at a joint area. A pin extends from the joint area of the modular frame. A polymer solution is dispensed through a syringe, and the pin passes by and contacts a droplet of the polymer solution as the modular frame rotates. Fibers are formed by using the pin to draw out the fibers from the droplets of the polymer solution. The fibers are deposited on the modular frame. In some cases, the plurality of frame sections of the modular frame are arranged on a base in a first arrangement. After the fibers are deposited, the plurality of frame sections are reconfigured into a second arrangement different from the first arrangement to form a fiber component of an air flow device.

Abstract: A photovoltaic module has a flexible backing substrate, a plurality of photovoltaic cells, and an electrical conduit. The photovoltaic cells are mounted on the backing substrate. Each photovoltaic cell has a metallic article, the metallic article including a plurality of electroformed elements comprising a cell interconnection element integral with a continuous grid having a plurality of first elements intersecting a plurality of second elements. The electroformed elements are interconnected and integral, with the continuous grid in contact with the light-incident surface of the photovoltaic cell. The cell interconnection element extends beyond the light-incident surface and couples the continuous grid to a neighboring photovoltaic cell. The electrical conduit has a flexible strip of electrically conductive material.
