“…However, it is observed in some research works that using the air channel with PVT‐TE collector is less effective compared to water‐based PVT‐TE collector due to low density, less specific heat capacity, and low thermal conductivity of air 25 . Additionally, during the process of heat convection and conduction; water is more efficient than air 26 .…”

Summary In this work, performance analysis of the photovoltaic‐thermoelectric with serpentine water collector (PV‐TE‐SWC) has been carried out. For extracting the heat from the back surface of the combined PV‐TE system and to maintain a temperature gradient, a serpentine‐type tube and sheet water collector is proposed. The electrical efficiency of the designed PV‐TE‐SWC is compared with the experimental and theoretical results on a similar type of collector from the literature to validate the proposed simulated model. After that, the performance in terms of annual useful thermal energy, annual overall electrical energy, annual useful overall thermal energy, annual thermal exergy, and annual overall exergy of the PV‐TE‐SWC (case‐I) have been carried out and compared with the outcomes of a recent state‐of‐art study on PV‐TE air collector (case‐II). The average improvement in hourly overall electrical efficiency and hourly exergy gain of case‐I have been found by 5.72% and 31.34%, respectively, concerning case‐II. The study shows that the annual performance parameters, that is, overall electrical energy, overall thermal energy, and overall exergy have been observed considerably higher for case‐I by 8.4%, 14.8%, and 41.7%, respectively concerning case‐II. Further, environmental cost analysis based on the price of carbon dioxide emission has also been computed based on annual overall thermal energy and overall exergy generated from the collector.

“…[68] Also, the PV-TE generally requires concentrators to achieve such a high temperature, which is unnecessary for other heat extraction methods. [69,70] Tiwari et al [71] analyzed photovoltaic, thermoelectric flat plate collectors, which integrates the TE and water-based heat sink at the bottom of the PV panel (see Fig. 10).…”

Photovoltaic technology is a direct and effective way to utilize solar energy. The mismatch between the absorption band of solar cells and the solar light band restricts solar energy's efficient use. Full-spectrum conversion of solar energy with spectral modification and coupling solar thermal application are reviewed. Additionally, implementing machine learning (ML) methods to improve solar energy utilization is also examined. With the utilization of up-conversion materials for solar cells, the solar-energy-utilization efficiency is enhanced. Combining PV and thermal applications have been validated to be promising for improving efficiency. With the development of computer science and the urgent need to design solar energy materials and forecast PV performances, ML methods in solar energy utilization have been successfully implemented into solar energy utilization.

“…Apart from exclusive numerical and analytical studies, few researchers have also performed experimental studies, either indoor [27][28][29][30][31][32][33][34] or outdoor. [35][36][37][38][39] Both types are important as indoor tests are preferred to precisely control the operating parameters, whereas outdoor testing is crucial to gauge the in-field effect. In both cases, various cooling mediums (active and passive methods) researched are an ice-water mixture, water, air, nanofluids, and PCM, as listed in Table 1.…”

Numerous studies have emphasized the role of cooling in maximizing the energy conversion efficiency of a photovoltaic (PV) module. Amongst them, the energy and exergy analyses of PV-thermoelectric generator (PV-TEG) hybrid systems with evaporative cooling have been rarely investigated. Hence, the present experimental study focuses on the performance comparison of PV-TEG hybrid system with different cooling techniques. The parameters studied are panel temperature, energy and exergy efficiency, power output, and I-V and P-V characteristics. As the indoor and outdoor radiation spectrum varies
