Abstract:This paper addresses the progress of my research up until my senior year. My main research topic is fabricating high efficiency mono-crystalline silicon photovoltaic (Si PV) with mechanically flexible and stretchable designs, and light trapping structures. My research group recently reported a strategy, in which modules consist of large-scale arrays of small, interconnected ultrathin (i.e.1-20 μm) Si microcells (μ-bar cells) for mechanically flexible and semitransparent formed by anisotropic etching of bulk wafers and integrated with a soft printing technique. These techniques use procedures developed for thin Si electronic devices and allow for the fabrication of compact modules out of hundreds or thousands of such microcells, with good efficiencies and the capacity to exploit Si in unconventional module designs. There are many more interesting applications regarding these Si microcells structures. In this regard, I will introduce my research goals and describe procedures for the fabrication of silicon microstructures, stretchable photovoltaic devices, and light trapping structures on Si.
