“…For both types of CPV + modules, the low per-area cost of energy from Si cells makes them attractive for use on the module backplane as diffuse light collectors. Emerging alternatives based on perovskites, organics, epitaxial lift-off III-Vs, each with the additional possibility of use in advanced luminescent concentration schemes (31,(40)(41)(42)(43)(44)(45), may also be considered. The bandgaps, in particular, are important.…”

“…Here, transfer printing enables high-volume manufacturing and assembly of cells with these small dimensions (26)(27)(28)(29)(30)(31)(32). The ball lenses, as secondary optics, improve manufacturing tolerances, produce uniform irradiation profiles on the cells by correcting for chromatic aberration, and expand the acceptance angle to nearly ±1°even at concentration ratios of >1,000 (22).…”

Emerging classes of concentrator photovoltaic (CPV) modules reach efficiencies that are far greater than those of even the highest performance flat-plate PV technologies, with architectures that have the potential to provide the lowest cost of energy in locations with high direct normal irradiance (DNI). A disadvantage is their inability to effectively use diffuse sunlight, thereby constraining widespread geographic deployment and limiting performance even under the most favorable DNI conditions. This study introduces a module design that integrates capabilities in flat-plate PV directly with the most sophisticated CPV technologies, for capture of both direct and diffuse sunlight, thereby achieving efficiency in PV conversion of the global solar radiation. Specific examples of this scheme exploit commodity silicon (Si) cells integrated with two different CPV module designs, where they capture light that is not efficiently directed by the concentrator optics onto large-scale arrays of miniature multijunction (MJ) solar cells that use advanced III-V semiconductor technologies. In this CPV + scheme ("+" denotes the addition of diffuse collector), the Si and MJ cells operate independently on indirect and direct solar radiation, respectively. On-sun experimental studies of CPV + modules at latitudes of 35.9886°N (Durham, NC), 40.1125°N (Bondville, IL), and 38.9072°N (Washington, DC) show improvements in absolute module efficiencies of between 1.02% and 8.45% over values obtained using otherwise similar CPV modules, depending on weather conditions. These concepts have the potential to expand the geographic reach and improve the cost-effectiveness of the highest efficiency forms of PV power generation.photovoltaics | multijunction solar cells | concentration optics | diffuse light capture T he levelized cost of electricity (LCOE) is a primary metric that defines the economic competitiveness of photovoltaic (PV) approaches to electrical power generation (1). As the performance of the highest efficiency single-junction flat-plate PV modules begins to reach theoretical limits, research toward cost reductions in such technologies shifts from performance to topics related to materials utilization and manufacturing (2-5). By contrast, the efficiencies of multijunction (MJ) solar cells based on III-V compound semiconductors continue to improve steadily, at a rate of ∼1% per year over the last 15 y, due largely to progress in epitaxial growth processes, mechanical stacking techniques, and microassembly methods for adding junctions that further maximize light absorption and minimize carrier thermalization losses (6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20). Record MJ cell efficiencies now approach ∼46.0%, with realistic pathways to the 50% milestone (5). For economic deployment, however, the sophistication and associated costs of these cells demand the use of lenses, curved mirrors, or other forms of optics in conjunction with a mechanical tracker to geometrically concentrate incident direct sunlight in a manner tha...

“…The system being utilized to its fullest by providing heat, cooling and electricity based on the demand. Even though many researchers in the literature have discussed these ideas [67,68,70,71,73] the general trend is to focus only on one condition while this design corresponds to various conditions. The effect of having Net-Zero energy houses is massive to the environment if applied on large scale [69].…”

Abstract-Photovoltaic Thermal (PV/T) combine the solar thermal and photovoltaic systems. This technique benefits from both light and heat of the solar radiation to produce electricity and hot fluids. Research in PV/T systems is rapidly growing with more methods and techniques to increase the overall efficiency, reduce the cost, improve the modeling, and maintain the system for long periods of time and employing them for suitable application. The paper aims to study some of the research conducted in this field in order to understand and derive key points to producing more research and providing constructive criticism for the work presented. Also a detailed explanation of PV/T systems' principles and operation is presented. Classifications of PV/T in terms of absorber design, shape of pipes, PV configuration, type of working fluid (base-fluid) and type of PV panels are all discussed in the literature survey. Finally, it is concluded that there is a clear lack in electrical, economic and environmental evaluations, where most of articles in PV/T are dominated by the thermal study of the system.
