“…The system presented in this paper is the first to use multi-quantum-well cells. Using traditional Si cells, the reachable overall efficiency of the system is about 5% [5], while with GaSb cells the overall efficiency is around 8% [1,2,6]. With multi-quantum-well cells an overall efficiency of around 25% is possible, if the experimental data can confirm the expected high-energy conversion efficiency of such cells [10,11,13].…”

“…It is equipped with a heat regenerator from high-temperature exhaust gas able to boost the overall efficiency of the system. Together with aerospace [11] and military applications, other possible applications of TPV have been investigated, such as electric power generators or electric vehicles [1,2,5]. Schubnell's TPV application to residential heating systems gives an example of the potential everyday use of thermophotovoltaics in small co-generation systems that produce electricity and heat.…”

“…Interest in thermophotovoltaics started in the early 1960s when the military industry began to look for alternative ways to produce electric power with direct conversion of energy, without moving parts, reducing noise and using any source of energy. It has only been in the last decade that some technological constraints, which have limited the diffusion of these devices, have been overcome and thermophotovoltaic (TPV) systems have been built [1][2][3][4][5][6]. A TPV system is a device capable of converting heat directly into electric power.…”

A thermophotovoltaic (TPV) generator for electric vehicles has been designed and developed. In this paper we focus on the combustion system and the heat regenerator. The system has been designed to work as a range extender for electric vehicles. This solution would provide energy always available on the vehicle, which would run even if the battery level were low. Several configurations for the burner and for the heat exchanger have been investigated and a comparison of these is presented. The different solutions have been studied both theoretically and experimentally. In this paper, we report on the work carried out to build a TPV device capable of yielding 6 kW of electric power to recharge the battery pack of an electric city-car. The project has been divided into four steps: (1) pre-design of different configurations of the burner and heat exchanger using non-commercial software 'TPV Design Tool 1.0'; (2) testing of the pre-designed generators with a CFD code (Fluent 6); (3) testing of the chosen configurations on the experimental bench to validate the results from CFD simulations and to highlight technological limits of the chosen configurations; (4) selection of the best configuration. After the design and testing of the devices, a two-burner modular configuration has been proven to be a good compromise between the geometric constraints and the objectives of the project. The designed generator is relatively compact and light with good efficiency and emissions performance.

“…While most thermophotovoltaic devices used in systems have been made from low-bandgap (<1.0 eV) semiconductors, some researchers have analysed the use of silicon solar cells for residential heating applications [11]. Silicon solar cells have been used in a TPV generator made by the Paul Scherrer Institute that produced 15 W with 1.1% efficiency [12].…”

To illustrate the variety and complexity of thermophotovoltaic (TPV) system designs, the present status of selected systems, ranging in power output from 50 W to 2 kW, is reviewed. The design and analysis of each of these power systems is complex due to the interactions among the radiator, photonic cavity and filter/semiconductor device elements. To draw meaningful conclusions and aid the development of new power systems, a methodology for measuring and predicting the performance of system designs is required. To first order, this includes an understanding of the semiconductor diode characteristics, emitter/filter spectra and radiative properties of the system components.

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.
