THERMOPHOTOVOLTAIC SYSTEM Meaning and
Definition
-
A thermophotovoltaic (TPV) system refers to a specialized device that harnesses heat energy and converts it into electricity using the principles of thermophotovoltaics. This advanced technology combines the concepts of thermodynamics and photovoltaics to generate power in a highly efficient manner.
At its core, a thermophotovoltaic system consists of three main components: a heat source, a selective emitter, and a photovoltaic (PV) cell. The heat source, typically a high-temperature source like a burner or a concentrated solar receiver, emits thermal radiation. The selective emitter, a specially designed material, absorbs a particular portion of this radiation while reflecting the rest. By applying advanced materials engineering, the selective emitter allows a high-energy photon flux tailored to the bandgap of the PV cell to pass through, maximizing the system's efficiency.
The PV cell, specifically designed for thermophotovoltaics, is capable of converting the absorbed photons into electrical energy. This cell is optimized to operate at high temperatures, often exceeding 1000°C, which allows it to take advantage of the intense thermal radiation. The generated electricity can then be utilized for various applications, such as powering electronic devices or being integrated into power grids.
Thermophotovoltaic systems have the potential to offer a more sustainable and efficient energy-conversion solution, especially in high-temperature applications and in situations where direct sunlight is not readily available. With ongoing research and development efforts, these systems aim to enhance their conversion efficiencies, extend their operational lifetimes, and broaden their range of applications in the fields of renewable energy and sustainable power generation.

Etymology of THERMOPHOTOVOLTAIC SYSTEM
The word "thermophotovoltaic" is a combination of three different terms: "thermo-", "photo-", and "voltaic".
- "Thermo-" comes from the Greek word "thermos", meaning "heat" or "warmth". It is commonly used as a prefix in scientific terms related to heat or temperature.
- "Photo-" also comes from Greek, specifically from the word "phōs" meaning "light". It is used as a prefix referring to light or electromagnetic radiation.
- "Voltaic" refers to an electric current or voltage and is derived from the Italian physicist Alessandro Volta, who invented the first electric battery.
Therefore, the term "thermophotovoltaic" describes a system that converts heat (thermal energy) into electricity (photovoltaic) using a combination of thermal and photonic processes.
