Thermoradiative conversion could, in principle, be used for energy conversion for any thermal source. The original proposals were for terrestrial applications.
In a photovoltaic cell, thermal energy turns into electrical energy. This electrical energy is direct current (DC). The inverter converts the DC to alternating current (AC). The coolant attached to the system maintains the temperature of the cell by reducing the overheating of the photovoltaic cell.
The working principle of solar cells is based on the photovoltaic effect of semiconductor p-n junctions. The so-called photovoltaic effect is the effect in which, when an object is exposed to light, the state of charge distribution changes to produce an electromotive force.
Photovoltaic (PV) cells are popularly considered a feasible device for solar energy conversion. However, the temperature on the surface of a working solar cells can be high, which significantly decreases the power conversion efficiency and seriously reduces the cell life.

Waste heat is the low-grade energy heat generated by the work done in the system. Systems such as machines, ovens and stoves emit the heat for the duration of their work. Waste heat has been obtained during production phase from the furnace, from the heater (oven wall, stove etc.) and from the flue gas [ 1–4 ].
