“…A monocrystalline silicon (mc-Si) cell manufactured by Big Sun Community Solar (San Antonio, TX, USA) was selected for this study based on the widespread inclusion of this PV technology in the majority of the low to medium C-PVT systems [ 24 ]. To limit the fundamental losses of this PVT system, the luminescent down-shifting materials were integrated into the filters design through the implementation of highly fluorescent organic ligands.…”

“…In other words, the internal structure of the liquid optical filters acts to partition the solar spectrum into its respective ‘thermal’ and ‘electrical’ components. Consequently, the cooperative interactions between the two collection elements can be maximised [ 24 ]. Furthermore, SBS allows for the characteristics of the filter to be readily modified or maintained through the simple replacement of the working fluid [ 18 , 25 ] increasing the cost effectiveness of this strategy when compared to the other alternative hybridisation approaches [ 11 , 19 ].…”

Under these conditions it is essential to identify materials which not only possess an exceptionally high transmittance over the spectral window where the PV technology is most efficient, but also materials which exhibit exemplary heat-transfer capabilities [ 24 ]. Hence, the desire to produce and evaluate the optical and thermophysical properties of different combinations of material additives (e.g., Ag, Cu, Au, carbon, oxides nanoparticles (NPs) etc.)…”

Exploiting solar energy using photo-thermal (PT) and/or hybridised photovoltaic/thermal (PVT) systems can represent a viable alternative to the growing demand for renewable energy. For large-scale implementation, such systems require thermal fluids able to enhance the combined conversion efficiency achievable by controlling the ‘thermal’ and ‘electrical’ components of the solar spectrum. Nanofluids are typically employed for these purposes and they should exhibit high heat-transfer capabilities and optical properties tuned towards the peak performance spectral window of the photovoltaic (PV) component. In this work, novel nanofluids, composed of highly luminescent organic molecules and Ag nanoparticles dispersed within a base fluid, were tested for PT and PVT applications. These nanofluids were designed to mimic the behaviour of luminescent down-shifting molecules while offering enhanced thermo-physical characteristics over the host base fluid. The nanofluids’ conversion efficiency was evaluated under a standard AM1.5G weighted solar spectrum. The results revealed that the Ag nanoparticles’ inclusion in the composite fluid has the potential to improve the total solar energy conversion. The nanoparticles’ presence minimizes the losses in the electrical power component of the PVT systems as the thermal conversion increases. The enhanced performances recorded suggest that these nanofluids could represent suitable candidates for solar energy conversion applications.

“…Wolf developed an initial hybrid thermal/photovoltaic system to enhance PV electric output and utilize the absorbed heat simultaneously [5]. Recent research has been applied to achieve the same goal by utilizing either water or air as cooling fluid in order to absorb the excess heat stored in PV modules [6,7]. A spike in temperature can reduce the amount of power generated by about 0.5% for every 1 • C increase, so researchers are trying to keep the temperature of PV modules at 25 • C [8,9].…”

The proposed study aims to estimate and conduct an investigation of the performance of a hybrid thermal/photovoltaic system cooled by nanofluid (Al2O3) utilizing time-series deep learning networks. The use of nanofluids greatly improves the proposed system’s performance deficiencies due to the rise in cell temperature, and time-series algorithms assist in investigating its potential in various regions more accurately. In this paper, energy balance methods were used to generate the hybrid thermal/photovoltaic system’s performance located in Tabuk, Saudi Arabia. Moreover, the generated dataset for the hybrid thermal/photovoltaic system was utilized to develop deep learning algorithms, such as the hybrid convolutional neural network (CNN) and long short-term memory (LSTM), in order to estimate and investigate the thermal/photovoltaic performance. The models were evaluated based on several performance metrics such as mean absolute percentage error (MAPE), root mean square error (RMSE), mean absolute error (MAE), and the coefficient of determination (R2). The results of the evaluated algorithms were compared and provided high accuracy ranges of 98.3–99.3%. It was observed that the best model among the others was CNN-LSTM, with an MAE of 0.375. The model was utilized to investigate the electrical and thermal performance of the hybrid thermal/photovoltaic application cooled by Al2O3 in addition to the hybrid thermal/photovoltaic cell temperature. The results show hybrid thermal/photovoltaic cell temperatures could be decreased to 43 °C, while the average daily thermal and electrical efficiencies were raised by 15% and 9%, respectively.

In this paper, the performances of a novel hybrid solar system using the Al2O3 nanofluid and pure water as a heat transfer fluid to operate a single-effect lithium bromide absorption chiller is investigated. In which the performance of the proposed system using the nanofluid during winter and summer under mixed and forced convection are evaluated. In which, the performances of solar collector are investigated experimentally, and the output performances of the water-LiBr absorption chiller system is conducted numerically using MATLAB platform. The results show that the obtained Reynolds number of the heat transfer fluid is laminar flow in summer with the maximum values 1700and 1600 for nanofluid and water, respectively; and transitory flow in winter with the maximum values of 2200 and 2100 for nanofluid and pure water, respectively. The proposed hybrid system achieves approximately 54%, 36%of maximum thermal efficiency during the winter and the summer, respectively. The obtained performance show that the absorption cycle at positive evaporation temperatures is very appreciable using the nanofluid as working fluid during both seasons and quite satisfactory by using the water during summer and winter seasons. Overall, proposed system has potential for further development in solar cooling system.
