Photovoltaic and thermal (PVT) energy systems are becoming increasingly popular as they maximise the benefits of solar radiation, which generates electricity and heat at the same time.
Design and development of photovoltaic thermal collector (PVTC) are reviewed. Electrical efficiency of PVTAC and PVTWC is found as 4–24% and 5.1–15.8%. Thermal efficiency of PVTAC and PVTWC is found to be in the range 27–87%. Honeycomb plate is better in terms of thermal efficiency for PVTAC.
The material used to make solar cells has a substantial influence on the performance of the PVT system. The previous study has revealed that there is still a large future research scope accessible in additional collar cell technologies, for instance, amorphous silicon and gallium arsenide.
Over time, their efficiency has gradually increased, with the most recent technology achieving conversion efficiencies of over 20%; however, because of their sensitivity to temperature, shading, dirt, dust accumulation, and aging of the materials, approximately 80% of the incident solar energy is dissipated as heat in silicon solar cells [3, 7, 8].
The study was carried out for the solar radiation in the range of 200–1000 W m −2 and ambient temperature of 20 °C. The operating temperature of a PV module was reported as 50-59 °C. It has been notified that the thermal efficiency improved with the length of the collector, while the electric efficiency reduced.
To compare the performance of electrical and thermal efficiency, a single photovoltaic module, a conventional air-PVT, a glazed single pass PVT, and a glazed double pass PVT were studied. Heat balance equations and various thermal and electrical parameters are used to create a numerical model.
