Abstract: B55.00010 : From Quantum Dot Heat Engines to Hot-Carrier Photovoltaics*
1:42 PM–2:18 PM
This proof-of-performance of efficient energy harvesting from electrons is directly relevant to the concept of hot-carrier solar cells or thermophotovoltaics, where the aim is to boost energy conversion efficiency by harvesting heat from non-equilibrium electrons . I will present our progress towards implementing this principle in heterostructure nanowires.
