The Quantum Energy and Sustainable Solar Technologies Engineering Research Center (QESST ERC) is sponsored by the National Science Foundation and Department of Energy to advance photovoltaic science and technology. QESST is developing new photovoltaic technologies to transform electricity generation in a sustainable way by addressing barriers like performance, cost and manufacturability. An interdisciplinary team from universities and companies is working on innovations in materials science, energy conversion processes, and manufacturing. The goal is to circumvent tradeoffs between performance and cost to exceed today's goals for solar energy.
