Semiconductor Architectures for Generation of Energy
SAGE Research Lab
Welcome to the de Lafontaine Semiconductor Architectures for Generation of Energy (SAGE) Lab at the University of Ottawa!
About the group
Our research explores the fundamental and applied aspects of energy-conversion technologies with a focus on disruptive device architectures that capture light, heat, and beta radiation to generate electrical power. We design, model, fabricate, and characterize next-generation energy-conversion micro-scale devices, including:
-Betavoltaics, new designs that generate high power densities for long operational life batteries
-Photovoltaics, new techniques to enhance solar energy harvesting efficiency and lower manufacturing costs
-Thermophotovoltaics, new techniques to increase the conversion efficiency of heat into electricity
Our approach integrates multiphysics modeling, nanofabrication techniques, artificial intelligence, and advanced characterization methods to optimize device performance. By bridging material science, photonics, and microengineering, we aim to push the boundaries of energy conversion efficiency, miniaturization, and integration for applications ranging from space systems and telecommunications to autonomous sensors and biomedical implants. Our work contributes to the development of compact, high-efficiency energy solutions that support the global energy transition.
