“…Table 1a shows a sample of data from the experiments. Many researchers have studied power generation using PV generators or Stirling engines [30][31][32][33][34] others studied the heat transfer from a flat plate embedded in a porous medium [35][36][37]. It was clear from research that adding a high thermal conductivity porous layer on a flat plate increases the heat transfer from the plate [38].…”

“…These factors may very well affect the efficiency and the profitability of PVs. For instance, several studies have discussed the negative effects of elevated temperatures on PV modules and suggested different methods of improving their efficiencies [11][12][13]. Other studies have investigated the effect of dust on PV modules [14,15].…”

The cooling of PV models is an important process that enhances the generated electricity from these models, especially in hot areas. In this work, a new, active cooling algorithm is proposed based on active fan cooling and an artificial neural network, which is named the artificial dynamic neural network Fan cooling algorithm (DNNFC). The proposed system attaches five fans to the back of a PV model. Subsequently, only two fans work at any given time to circulate the air under the PV model in order to cool it down. Five different patterns of working fans have been experimented with in this work. To select the optimal pattern for any given time, a back propagation neural network model was trained. The algorithm is a dynamic algorithm since it re-trains the model with new recorded surface temperatures over time. In this way, the model automatically adapts to any weather and environmental conditions. The model was trained with an indoor dataset and tested with an outdoor dataset. An accuracy of more than 97% has been recorded, with a mean square error of approximately 0.02.

“…More recent research aims to produce various flux distributions in 2D and 3D space through corresponding optical fiber bundle arrangements [23]. However, contrary to high-temperature applications like those envisaged by Nakamura, most of the current studies deal with illumination and hybridization with PV systems (e.g., [24,25]) or even with photocatalytic wastewater treatment (e.g., [26]) or photocatalytic CO 2 reduction [27], and, to our knowledge, no experimental demonstration has been carried out yet assuming the bundle of optical fibers in the receiver position on top of a high-concentration central tower (as was envisaged by González et al [18]).…”

After being adequately captured and concentrated, solar radiation can be conducted by optical fiber bundles/cables and directly used for illumination (lighting) or heating of confined spaces, or indirectly used by converting it in other forms of energy (e.g., for producing electricity). This article reports preliminary tests conducted on a 7-m-long optical fiber bundle/cable with an effective aperture circular area of 14 mm in diameter, specially designed and manufactured by a leading company to transmit up to 1000 Wth of unfiltered concentrated sunlight. The cable was tested in the typical receiver position at the top of a solar concentration central tower. The main purpose was the experimental determination of the transmission efficiency of the cable in the function of the incidence angle using selected groups of heliostats belonging to the heliostat field. The testing methodology proved to be capable of evaluating the performance of the cable. The cable withstood the tests without revealing any type of damage. The results obtained showed that the transmissivity of the cable is higher than 50% when the incidence angle of the solar radiation is lower than 14.7°, increasing sharply to circa 95% when the incidence angle is lower than 4.5°.
