David Needell

Graduate Student


David joined the Atwater group in 2015.  He works on the design, characterization, and fabrication of waveguides and coatings for Luminescent Solar Concentrators (LSC’s) with the ultimate goal of designing a novel solar device that combines traditional, flat-plate Silicon photovoltaics with active LSC’s to achieve high efficiencies at a substantially lower manufacturing cost.  David completed his undergraduate degree at Bowdoin College with a double major in Applied Mathematics and Physics with a minor in Computer Science.  His previous research investigated alternative, biohybrid solar devices at both Bowdoin College and at Vanderbilt University, with an emphasis in developing a Photosystem I (PSI), Silicon photovoltaic cell.
