  • ROBOTIC SYSTEMS FOR ADDITIVE MANUFACTURING
    Publication number: 20230211558
    Abstract: Systems and methods for additive manufacturing. In some examples, a system includes a frame defining an interior volume and an overhead robotic arm suspended from a gantry on a ceiling of the frame. The system includes manufacturing subsystems located within the interior volume of the frame. The system includes a control system configured for controlling the overhead robotic arm for parts movement among additive manufacturing processes using the manufacturing subsystems. The manufacturing subsystems can include one or more of: a microassembly station, an aerosol jetting print station, an intense pulsed light (IPL) photonic sintering station, a fiber weaving station, and a 3D printing station.

  • Methods for forming a perovskite solar cell
    Patent number: 10950794
    Abstract: A perovskite thin film and method of forming a perovskite thin film are provided. The perovskite thin film includes a substrate, a hole blocking/electron transport layer, and a sintered perovskite layer. The method of forming the perovskite solar cell includes depositing a perovskite layer onto a substrate and processing (for example, by sintering) the perovskite layer with intense pulsed light to initiate a radiative thermal response that is enabled by an alkyl halide additive.
