Abstract

Though the sun is our most abundant source of energy, existing solar power production methods can generate electricity only while the sun is shining. To shift to a truly sustainable energy grid, new green energy production techniques that function at night must be developed. Here we consider a “nighttime photovoltaic cell” that harnesses electricity from the flow of heat between the earth and the cold night sky. We discuss thermoradiative photovoltaics, the physics driving this photovoltaic technique, and the theoretical limits of such a device. We conclude with an analysis of this novel photovoltaic concept’s practical limits and integrability.
