“…The conversion of electricity effectively occurs at photon wavelengths near the λ c of a particular material. Assuming the highest photon-electricity conversion is achieved when λ c is approximately similar to the λ p , the suitable operating temperature as a function of bandgap energy can be expressed by Equation (5).…”

“…It is highlighted that the epitaxial GaSb TPV can reach approximately 96% of IQE when optimizing the emitter and base layer thickness to 0.22 and 10 µm, respectively. In the same vein, Rashid et al [ 5 ] investigated the effect of emitter layer region and compared the GaSb TPV cell performance with a Zn-diffused commercialized JX Crystals Inc device. Based on their simulation result, an efficiency increment from 4.70 to 7.88% was recorded with optimized emitter thickness and doping concentration under AM 1.5 illumination condition.…”

“…In comparison to a solar photovoltaic system, a TPV system works for a longer operation time at a lower radiator heating temperature [ 4 ]. A TPV system consists of four main devices: a generator to provide heat energy from the fuel combustion process, a radiator to translate the heat energy into an emission spectrum, a filter to coordinate the emission spectrum to a TPV cell, and lastly a TPV cell to convert the photon radiation into electrical energy [ 5 ]. A comprehensive analysis has been conducted in each component of the TPV system to enhance the overall performance.…”

Generally, waste heat is redundantly released into the surrounding by anthropogenic activities without strategized planning. Consequently, urban heat islands and global warming chronically increases over time. Thermophotovoltaic (TPV) systems can be potentially deployed to harvest waste heat and recuperate energy to tackle this global issue with supplementary generation of electrical energy. This paper presents a critical review on two dominant types of semiconductor materials, namely gallium antimonide (GaSb) and indium gallium arsenide (InGaAs), as the potential candidates for TPV cells. The advantages and drawbacks of non-epitaxy and epitaxy growth methods are well-discussed based on different semiconductor materials. In addition, this paper critically examines and summarizes the electrical cell performance of TPV cells made of GaSb, InGaAs and other narrow bandgap semiconductor materials. The cell conversion efficiency improvement in terms of structural design and architectural optimization are also comprehensively analyzed and discussed. Lastly, the practical applications, current issues and challenges of TPV cells are critically reviewed and concluded with recommendations for future research. The highlighted insights of this review will contribute to the increase in effort towards development of future TPV systems with improved cell conversion efficiency.

“…Although significant progress has been made in the last decade, coordination of multiple components in a TPV system is the main challenge for achieving a highperformance TPV system. This is mainly due to the optical and electrical losses within the system [18]. In principle, the energy of photons must be larger than the bandgap energy of the TPV cells to allow maximum electron-hole pair generation.…”

Rapid depletion of fossil fuels due to the growing demand for energy has resulted in a worldwide concern to improve energy conversion efficiency. Yet, the energy conversion of conventional fossil fuel power generation plants remains relatively low (less than 40%) and a huge amount of energy is wasted in the form of heat, leading to global warming issues. Recycling and recuperating even a small portion of energy losses could provide a huge impact on energy saving and minimize the reliance on fossil fuels. Thermophotovoltaic system appears to be a potential candidate to capture, recover, and convert waste heat energy into useful electricity. This paper presents an overview of the recent development of thermophotovoltaic technology for waste heat recovery applications. Each component in the thermophotovoltaic system including thermophotovoltaic generator/heat source, thermal emitter, spectral filter and thermophotovoltaic cells is vital and can be engineered to achieve a better heat-to-electricity conversion efficiency. Recently, researchers have shown great interest in near-field thermophotovoltaic systems where higher power intensity can be captured by the thermophotovoltaic cell, thus improving the overall system performance. Furthermore, the potential locations for energy scavenging in thermal power plants is investigated based on the on-site temperature measurement. In Malaysia, it is estimated that around 3,831 GWh of waste heat energy could be saved in operational thermal power plants. This review will contribute to the knowledge for future development thermophotovoltaic systems in waste heat recovery applications while summarizing the potential locations for energy scavenging in thermal power plants.
