“…Broadband radiator establishes the emission across a wide range of wavelength for temperature range between 1000 to 2000 K [32,37]. Examples of broadband radiators are alumina, zirconia, magnesia, silica, yttria, and more, which possess a major challenge in low thermal shock resistance and low emissivity [38].…”

“…A radiator emits electromagnetic energy by translating heat from generators into an emission spectrum to provide appropriate receiver cell sensitivity [ 22 ]. Selective radiators such as silicon carbide (SiC), tungsten (W), W-SiO 2 rare-earth oxide, and photonics crystal (PhC) provide narrow spectral range emission by enhancing in-band radiation and suppressing out-of-band radiation [ 28 , 29 , 30 , 31 , 32 , 33 , 34 ]. There are two significant types of selective radiators, namely the rare-earth oxide radiator and the broadband radiator [ 35 ].…”

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.

“…The selective emitters were generated with several techniques; grating structures using micro/nano-scale fabrication technique [36], magnetic polaritons [37], and metamaterials such as (i) epsilon-near zero [38], (ii) passivated platinum and alumina [17], and (iii) alternate tungsten and alumina [39]. There are several types of selective emitters that have been discussed in the literature, which are silicon carbide (SiC) [7], tungsten (W) [40], rareearth oxide [41], and photonics crystal (PhC) [42] [43]. Among the selective emitters, rare-earth oxide is an isolated ion, serves as the most popular candidate for selective emitter.…”

Recent Development of Thermophotovoltaic System for Waste Heat Harvesting Application and Potential Implementation in Thermal Power Plant

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.

“…Another reason for this development is connected with thermophotovoltaic power converters. It was shown that materials with bandgap energy lower than 0.7 eV are very promising for thermophotovoltaic applications [7,8]. Over the emitter temperature range 1000-2000K the optimum bandgap for maximum electrical power density output is around 0.5-0.6 eV [7, 81, decreasing slightly for lower temperatures.…”

The paper presents the results of the development of AIGaAs/GaAs and GaSb cells, manufactured for tandem solar cells and designed for point and line-focus concentrator modules. The maximum efficiency of 23-23.6% (25'C, AMO) under 20-70 suns was achieved in the AIGaAs/GaAs infrared transparent cells with prismatic cover. The efficiency of 27.5% under AM1.5, 140 suns has been achieved.. The cells based on GaSb homo-junctions, Zn-diffused structures have been developed for tandems and thermophotovoltaic (TPV) applications. AM 1.5 efficiencies as high as 6.7% behind the GaAs filter for concentration ratio of 240 suns were achieved.Lattice matched p-n InGaSbAs-nGaSb heterostructures have been fabricated by LPE and Zn-diffusion method. The longwavelength edge of photosensitivity of these cells is 2.15-2.2 pm. IhlTRODUCTlONThe tandem solar cells have been realized recently in both mechanically stacked [l] and monolithic [2,3] constructions. The maximum efficiencies of about 30% (AMO) and 35% (AM 1.5) were achieved in a mechanically stacked concentrator tandem solar cells on the basis of AlGaAs/GaAs top cells and GaSb bottom cells [l]. MOCVD has become the main method for preparation of high efficiency AIGaAs/GaAs cell heterostructures. The nontoxic, inexpensive low-temperature LPE-method was used in our work for reproducible growth of the AIGaAs/GaAs structures [4, 51. The work on development of the GaSb and InGaSbAsjGaSb structures for tandems and thermophotovoltaics is in progress. INFRARED TRANSPARENT AIGaAs/GaAs SOLAR CELLSAIGaAs/GaAs heterostructures were fabricated by low temperature (600-400°C) liquid phase epitaxy [4,5].
