Thermophotovoltaic (TPV) energy conversion is a direct conversion process from heat to electricity via photons.A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object.
The British imperial units and U.S. customary units for both energy and work include the foot-pound force (1.3558 J), the British thermal unit (BTU) which has various values in the region of 1055 J, the horsepower-hour (2.6845 MJ), and the gasoline gallon equivalent (about 120 MJ).
In English, the Greek and Latin words occur in poetry as personifications of the Sun, Helios (/ ˈ h iː l i ə s /) and Sol (/ ˈ s ɒ l /), [2] [1] while in science fiction Sol may be used to distinguish the Sun from other stars. The term sol with a lowercase s is used by planetary astronomers for the duration of a solar day on another planet ...

Solar irradiance spectrum at top of atmosphere, on a linear scale and plotted against wavenumber.. The solar constant (G SC) measures the amount of energy received by a given area one astronomical unit away from the Sun.
Electricity generation is the process of generating electrical energy from other forms of energy.. The fundamental principle of electricity generation was discovered during the 1820s and early 1830s by the British scientist Michael Faraday.
Of or relating to the Sun. Solar telescope, a special purpose telescope used to observe the Sun; A device that utilizes solar energy (e.g. "solar panels"); Solar calendar, a calendar whose dates indicate the position of the Earth on its revolution around the Sun
In physics, natural unit systems are measurement systems for which selected physical constants have been set to 1 through nondimensionalization of physical units.For example, the speed of light c may be set to 1, and it may then be omitted, equating mass and energy directly E = m rather than using c as a conversion factor in the typical mass–energy equivalence equation E = mc 2.
