The theoretical potential for converting excess heat from the iron and steel sectors in Turkey into electricity by the use of thermophotovoltaic (TPV) systems is investigated and analyzed. The TPV usage in this industry is numerically investigated because this sector is in the leading position in terms of energy consumption in industrial sectors. Using the iron and steel industry waste heat energy data, it is shown that the energy conversion efficiencies of the TPV systems with the photovoltaic (PV) cell modules of In0.2Ga0.8As0.18Sb0.82 and GaSb are 7.31 % and 2.04 %, respectively. When using TPV systems in the Turkish iron and steel sectors for waste heat energy potential, it is calculated that 29.88 MJ per year can be generated with GaSb cells, and 1.076 PJ per year can be generated with In0.2Ga0.8As0.18Sb0.82 cells. Based on the results obtained from the numerical model in this study, some specific advice for the applicability and the development of the high efficiency TPV conversion systems is proposed.

“…Besides, the theoretical maximum efficiency of double junction cells is achieved when the low bandgap absorber is close to 1 eV, regardless of the irradiation or temperature conditions. Similarly, the advent of thermophotovoltaics has shifted the attention to narrower bandgap materials to efficiently absorb the infrared part of the spectrum in thermal waste recovery applications . Typical materials used in this field are Si, GaSb, copper indium gallium diselenide (CIGS), or Ge, with bandgaps in a similar range as In 6 S 7 .…”

Indium sulfide (In2S3) is a promising candidate for the replacement of CdS buffer layers in solar cell devices, while hexaindium heptasulfide (In6S7) presents interesting properties for its use as absorber material. In this work the fabrication of In2S3 microcolumns as well as novel In6S7 nanowires with diameters of about 70–120 nm is reported. The structures are grown following a thermal evaporation‐deposition method at temperatures between 900 and 1000 °C. Control of the phase and morphology of the structures is achieved through both the evaporation and deposition temperatures, which can be tuned separately. Energy dispersive spectroscopy shows no traces of residual oxygen, while X‐ray photoelectron spectroscopy indicates the presence of small amounts of oxygen incorporated at the surface of the structures. The In6S7 nanowires are found to be degenerated n‐type semiconductors, with the Fermi level above the conduction band minimum. The origin of this n‐type degeneracy is discussed in terms of S vacancies.

“…In the STPV system, the radiation density being incident on PV diode could be much higher than the solar irradiation intensity. Thus, it is also required that series resistance needs to be minimized, so that illuminated I-V characteristics of PV diode does not degrade severely under high radiation density [135]. Moreover, inside the STPV system, it is necessary to have an efficient cooling system to prevent degradation of the PV diode performance.…”

Solar thermophotovoltaics: reshaping the solar spectrum

et al. 2016

Abstract:Recently, there has been increasing interest in utilizing solar thermophotovoltaics (STPV) to convert sunlight into electricity, given their potential to exceed the Shockley-Queisser limit. Encouragingly, there have also been several recent demonstrations of improved systemlevel efficiency as high as 6.2%. In this work, we review prior work in the field, with particular emphasis on the role of several key principles in their experimental operation, performance, and reliability. In particular, for the problem of designing selective solar absorbers, we consider the trade-off between solar absorption and thermal losses, particularly radiative and convective mechanisms. For the selective thermal emitters, we consider the tradeoff between emission at critical wavelengths and parasitic losses. Then for the thermophotovoltaic (TPV) diodes, we consider the trade-off between increasing the potential short-circuit current, and maintaining a reasonable opencircuit voltage. This treatment parallels the historic development of the field, but also connects early insights with recent developments in adjacent fields. With these various components connecting in multiple ways, a system-level end-to-end modeling approach is necessary for a comprehensive understanding and appropriate improvement of STPV systems. This approach will ultimately allow researchers to design STPV systems capable of exceeding recently demonstrated efficiency values.
