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.

“…During 2015-2020, several researchers have tried to analyse the PVT technology by categorising the components through systematic reviews. The authors [28] investigated the effects of working fluid on the performance of flat plate PVT collectors by categorizing operating media, designs and climatic conditions. The review showed the electrical and thermal efficiencies of collectors for different physical locations and stressed the importance of nanofluid, bi-fluid, advanced materials to construct PVT collectors as part of future research.…”

A Review of Photovoltaic Thermal (PVT) Technology for Residential Applications: Performance Indicators, Progress, and Opportunities

Solar energy has been one of the accessible and affordable renewable energy technologies for the last few decades. Photovoltaics and solar thermal collectors are mature technologies to harness solar energy. However, the efficiency of photovoltaics decays at increased operating temperatures, and solar thermal collectors suffer from low exergy. Furthermore, along with several financial, structural, technical and socio-cultural barriers, the limited shadow-free space on building rooftops has significantly affected the adoption of solar energy. Thus, Photovoltaic Thermal (PVT) collectors that combine the advantages of photovoltaic cells and solar thermal collector into a single system have been developed. This study gives an extensive review of different PVT systems for residential applications, their performance indicators, progress, limitations and research opportunities. The literature review indicated that PVT systems used air, water, bi-fluids, nanofluids, refrigerants and phase-change material as the cooling medium and are sometimes integrated with heat pumps and seasonal energy storage. The overall efficiency of a PVT system reached up to 81% depending upon the system design and environmental conditions, and there is generally a trade-off between thermal and electrical efficiency. The review also highlights future research prospects in areas such as materials for PVT collector design, long-term reliability experiments, multi-objective design optimisation, techno-exergo-economics and photovoltaic recycling.
