Edward Sargent Environmental engineering – Energy & fuels

Edward Sargent’s research investigates the use of colloidal quantum dots to improve device performance and lower manufacturing costs. By tuning the size and properties of these semiconductor nanoparticles, photovoltaics can capture more of the sun’s energy, and infrared security cameras that can be manufactured on a large scale rather than current manual assembly methods. Additionally, his research team is interested in how nanomaterials can be used to sense the presence of disease indicators, and transform these signals into diagnostic devices.
