Wide-angle planar microtracking microcell concentrating photovoltaics

Rogers group will develop hexagonally-shaped microscale solar cells with 46% microcell efficiency. Additional work will focus on scale-up and integration of the concentrator stack, microcell array, tracking mechanics, and control electronics into a final, self-contained module package. Assembled modules will be tested for efficiency and tracking performance both in the laboratory and outdoors. Operational reliability will be assessed over the course of a three-week field test at a targeted module scale of 20x20 cm2. Collectively, these data will be used as the basis for a comprehensive technoeconomic analysis that quantifies the projected energy generation, manufacturing, and maintenance costs for a rooftop microtracking CPV system over its anticipated 20 year lifespan.
