Research Interests

Lenert’s research group focuses on understanding light-matter interactions and developing nanostructured materials that control the direction and wavelength of radiative transport, with various applications in solar energy conversion, energy storage, sustainable chemical production and infrared sensing. Such control is important to many problems related to transforming the world’s energy system to one with net-zero greenhouse gas emissions, including the lack of reliable and affordable renewable electricity and the growing need to decarbonize industry. His research team applies theoretical and computational tools to material design, implements advanced techniques for synthesis, fabrication, and characterization, and assesses device functional properties using custom-built experimental stations. Their path-breaking advances have led to large gains in light management in three areas: thermal photovoltaics, solar transparent aerogel materials, and robust nanophotonics.
