“…In terms of GaSb TPV cells implementation, Khvostikov et al [ 133 ] compared the performance of Zn-diffused GaSb-based TPV arrays connected in both series and parallel configuration. The parallel connection in the cylindrical system was found to produce a better performance when compared to the series connection in a conical system.…”

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.

“…Forty GaSb cells were linked in series and positioned on the cooling system's inner surface. The bottom surface totally reflected heat radiation, ensuring that it was absorbed completely by the cells (Zenker et al, 2001;Khvostikov et al, 2007). The solar collector collects the Sun's rays, which subsequently radiate to the absorber surface area.…”

Fossil fuels are now used to meet over 80% of the world’s energy demands, but they have the disadvantages of being unsustainable economically and polluting the environment. Solar energy is also one of the most desired alternative forms of renewable energy due to the quantity of direct sunlight among these sources. Due to the difficulties with solar cells, less than 1% of this energy is harvested and transformed into electricity. Notably, solar thermal and photovoltaic systems are the traditional methods for converting solar energy into electricity. It can be challenging to turn the solar energy captured by these systems into power. In contrast to conventional conversion methods, which involve converting solar energy directly into electricity, this article conducts a thorough investigation of solar thermophotovoltaic devices and the high-tech materials used in solar thermophotovoltaic systems as a solution to the conversion challenges.

We present a practical implementation of a solar thermophotovoltaic (TPV) system. The system presented in this paper comprises a sunlight concentrator system, a cylindrical cup-shaped absorber/emitter (made of tungsten coated with HÍO2), and an hexagonal-shaped water-cooled TPV generator comprising 24 germanium TPV cells, which is surrounding the cylindrical absorber/emitter. This paper focuses on the development of shingled TPV cell arrays, the characterization of the sunlight concentrator system, the estimation of the temperature achieved by the cylindrical emitters operated under concentrated sunlight, and the evaluation of the full system performance under real outdoor irradiance conditions. From the system characterization, we have measured short-circuit current densities up to 0.95 A/cm 2 , electric power densities of 67 mW/cm , and a global conversion efficiency of about 0.8%. To our knowledge, this is the first overall solar-to-electricity efficiency reported for a complete solar thermophotovoltaic system. The very low efficiency is mainly due to the overheating of the cells (up to 120 °C) and to the high optical concentrator losses, which prevent the achievement of the optimum emitter temperature. The loss analysis shows that by improving both aspects, efficiencies above 5% could be achievable in the very short term and efficiencies above 10% could be achieved with further improvements.
