Abstract
What is a Thermoradiative Diode and what role can they play in power generation?
(Spoiler: The device can generate power from any warm surface, including the Sydney opera house roof radiating into the cold night sky - effectively solar power at night!)
What do we need to do to make the most efficient solar cell and why can't it be 100% efficient?
This seminar describes the thermodynamics processes involved in achieving the ultimate limit of Solar Power Conversion.
• Landsberg Limit for Solar Power Conversion
• Fundamental losses in solar cells
• Multi-Junction Solar Cells : The Standard Path to High Efficiency
• Strain-Balance Quantum Well Solar Cell
• Observations from multi-junction PV manufacturing
• Australian Government Objective : Ultra Low Cost Solar PV
• Routes to improve Silicon PV Efficiency
• Molecular Singlet Fission
• Requirements for EQE > 100%
• Two technological pathways
• Electrical Power from Radiative Processes : Thermoradiative Conversion
• Thermoradiative and Thermophotovoltaic Power
• Thermoradiative power from body heat
