“…These techniques are of interest because they can reduce costs by improving the utilization of the cells and, in certain cases, by raising their efficiencies 3 . Conventional concentrators use focusing lenses and mechanical devices (that is, trackers) to maintain alignment with incident solar radiation 4,5 . This design can be attractive, particularly, when implemented with high efficiency compound semiconductor PV cells.…”

unconventional methods to exploit monocrystalline silicon and other established materials in photovoltaic (PV) systems can create new engineering opportunities, device capabilities and cost structures. Here we show a type of composite luminescent concentrator PV system that embeds large scale, interconnected arrays of microscale silicon solar cells in thin matrix layers doped with luminophores. Photons that strike cells directly generate power in the usual manner; those incident on the matrix launch wavelength-downconverted photons that reflect and waveguide into the sides and bottom surfaces of the cells to increase further their power output, by more than 300% in examples reported here. unlike conventional luminescent photovoltaics, this unusual design can be implemented in ultrathin, mechanically bendable formats. Detailed studies of design considerations and fabrication aspects for such devices, using both experimental and computational approaches, provide quantitative descriptions of the underlying materials science and optics.

“…Because of the focusing principle of Fresnel lens, HCPV panels or arrays rely on high-precise dual-axis solar tracking systems to keep themselves being perpendicular to the direct sunlight. There are many types of solar trackers have been reported and the design of trackers layout has been an essential consideration, especially for large scale installations [3,4]. At present, most HCPV power plants or research applications arrange their trackers' layout by experience [5].…”

Abstract:A new pattern of space coordinate system based on sun-tracking surface has been introduced in this paper. The calculation of shadow area between HCPV trackers has been simplified within this kind of coordinate system. The spaces between rows and columns of HCPV arrays can be calculated accurately. Therefore, an appropriate layout of trackers arrangement for a HCPV power plant can be determined and designed by use of this method.

Abstract. The paper presents a physical construction of a measurement stand consisting of a photovoltaic module operating in a fixed optimal configuration and in a solar tracking with a modified astronomical positioning. In order to reduce the electric energy consumption by two direct current linear motors system is positioned three times a day during winter months. Prepared energy balance, using annual measurements, confirmed the legitimacy of using twoaxis Sun tracking units for central Poland. Basing on the daily and monthly electricity production and solar irradiance for both photovoltaic units a mathematical formula with proposed correction factors is presented to calculate with good accuracy monthly electric energy generation for a fixed photovoltaic installation. The results of calculations were compared with measurements showing good correlation.
