Alexi Arango’s research focuses on advancing renewable energy by employing new semiconductors in the production of solar cells. His lab studies how quantum dots, molecular dyes, metal oxides, and other novel semiconductors can be incorporated into third generation solar cells that are both highly efficient and less expensive to manufacture than conventional solar cells employing silicon.
In 2010, Arango was awarded funding from the National Science Foundation’s Early-concept Grants for Exploratory Research Program for his project with Professor Janice Hudgings on increasing organic LED lifetime through improved thermal management. He also has received funding from the UMass NSF Center for Hierarchical Manufacturing, which brings together interdisciplinary groups to work on next generation devices. Arango has authored more than seven publications and holds more than seven patents in fields ranging from electrophoretic displays to light emitting diodes and solar cells.
In August 2011, Arango joined President Lynn Pasquerella’s team working with the African Center for Engineering Social Changes in Kenya. There, he consulted with rural communities on the feasibility of solar panel production in rural settings.
At MHC, Arango teaches courses on renewable energy, electromagnetism, and mathematical methods for scientists. In his teaching, Arango employs methods that have been proven by physics education research (PER) to increase students’ retention and conceptual understanding of the material.
