ECEN 4555 - Principles of Energy Systems and Devices


Catalog Data ECEN 4555 (3). Principles of Energy Systems and Devices. Develops principles underlying electronic, optical and thermal devices, materials and nanostructures for renewable energy. Course provides a foundation in statistical thermodynamics, and uses it to analyze the operation and efficiency limits of devices for photovoltaics, energy storage (batteries and ultra-capacitors), chemical conversion (fuel cells and engines), solid state lighting, heat pumps, cooling, and potentially harvesting zero-point energy from the vacuum.
