“…For the large-scale manufacturing, Fraas has recently pointed out that the cost of the PV diode (GaSb) circuits in TPV systems will be affordable when the volume is above 1 MW [131]. Since many STPV devices also use GaSb PV diodes, these estimates hold here as well.…”

“…For a zinc-diffused cell, values as low as −1.4 mV/K for V OC and −0.099%/K for the FF were identified between 25 and 75 ∘ C [130]. Finally, Fraas recently studied the potential fabrication costs of GaSb cells over time and reported that extrapolation to production volumes beyond 1 MW implied a substantial eventual lowering of costs [131].…”

“…Furthermore, when the fabrication scales up, not only the cost-effectiveness will be improved, but also the system conversion efficiency, based on prior experience in singlejunction PV manufacturing [131]. Based on the comparisons listed above, it is obvious that for certain applications, STPV may be a better option.…”

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.

“…In contrast, when these solar cells are used for terrestrial applications, they are used together with concentrator optics so that the cell cost becomes a small fraction of the overall system cost. This creates several challenges to overcome that stem from the increase in the irradiance on, and temperature of, the cell [3][4][5]. The MJ solar cell approach offers significant advantages and disadvantages that can only be understood by analysing a given design's composition and performance from a fundamental perspective.…”

High Concentrator Photovoltaics

Multijunction (MJ) concentrator solar cells are primarily constructed of III-V semiconductor materials. The high solar-conversion efficiencies of these devices are dependent on precise control of growth conditions using one of several techniques such as molecular beam epitaxy, metal organic chemical vapour, or metal organic vapour-phase epitaxy deposition. The use of several junctions in an MJ tandem stack allows these devices to achieve efficiencies that are not possible for single-junction devices. Their behaviour is consequently complex, but it can be understood through an examination of the external quantum efficiency and the temperature dependence of each cell in the stack. This chapter lays out a systematic approach for understanding the spectral and temperature dependence of the overall MJ device by way of consideration of its component subcells. The efficiency of the cell as a function of temperature and concentration is described for both lattice-matched and metamorphic triple-junction (TJ) solar cells. The electrical characteristics and current-voltage curves are described from these considerations, and the performance of MJ solar cells under real operating conditions are then presented by considering a term describing the overall thermal factor and another term for the spectral factor. These terms can be understood from the background presented in the previous sections. Finally, the power output for the complete cell incorporated into a Fresnel lens based high-concentration photovoltaic system is presented for a particular geographic location using meteorological data.

“…Solar power is one of the most considerable sustainable energy sources and has a paramount historical background, started with conversion of sun light into electricity in 19th century and then after observations on photovoltaic (PV) effect by Alexandre Edmond Becquerel, the electric energy production has been advancing and there is still a greater concern on the development of new technologies which would enable more efficient approaches [2].…”

Photovoltaics (PV) is becoming a mainstream electricity provider and the need for PV cells will spike compared to current demand. Solar power is based on obtaining electricity from solar radiation by using either photovoltaic cells or concentrated solar power (CSP). Both systems have different requirement to the area and advantages. However, there are several common disadvantages, which are related to the initial cost and regulatory issues that prevent investors from starting up such projects. Based on these premises the utilization of the solar power was examined in this study by highlighting the world's sustainable energy potential and investment statistics. Therefore research analysis related to the solar energy potential is presented as well. Although, the sustainable energy is the future of the world and requires slightly less amount of expense after installation, compared to conventional energy sources, the installation costs are the predominant factor of the utilization of the sustainable energy technologies. Furthermore, this study makes an overview of the world's solar power capacity today and makes prediction for the future. This study presents comprehensive market data together with forecasts for the short-run, while the role of PV is discussed considering the demand of energy.
