(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.
