ReviewI ConstantsI Periodic Table Part A Converting sunlight to electricity with solar cells has an efficiency of 15%. It's possible to achieve a higher efficiency (though currently at higher cost) by using concentrated sunlight as the hot reservoir of a heat engine. Each dish in the figure concentrates sunlight on one side of a heat engine, producing a hot-reservoir temperature of 530 °C. The cold reservoir, ambient air, is approximately 28 °C. The actual working efficiency of this device is...
