“…Energy is a highly discussed topic in society as it profoundly impacts a nation's prosperity and people's lives [1]. To achieve the goal of "carbon neutrality" by 2060, it is urgent to build a clean, low-carbon, and secure energy system [2]. The PV/T system is able to simultaneously generate electricity and heat, significantly improving energy utilization efficiency compared to the photovoltaic (PV) system or the ST system [3].…”

In this study, a two-stage system known as the PV/T-ST system with a series photovoltaic/thermal (PV/T) module and a solar thermal (ST) collector combining thermoelectric conversion technology is proposed. In the daytime, the PV/T module generates power and captures low-temperature heat simultaneously. The ST module achieves secondary heating of water and secondary thermal-electric output by the thermoelectric generators (TEG). In the nighttime, the water heated by day continues to circulate, providing heat for TEG, thus achieving round-the-clock electrical output. Theoretical research reveals that the system’s total electrical power reaches its maximum value at 11:57, measuring 97.43 W. The maximum heat gain amounts to 380.67 W. During the night, TEG operates continuously and experiences a gradual decline in electrical output, with an average electrical efficiency of 0.43%.

“…The photovoltaic thermal (PV/T) system is an effective research area to maximise the PV module’s generated power and provide an opportunity to supply the heat lost by the traditional PV system 16 . The combination of the PV and thermal system, also known as a hybrid PVT, enhances the efficiency of the PV cell and produces low-grade heat 17,18 . The optimisation coordination of the PVT system is one of the most critical research perspectives that is still in several laboratories because the actual commercial market does not have various types of high efficient PVT systems 19 .…”

Solar energy is the powerhouse where all potential and classified renewable energies lug their sources. The energy transformation from the Sun to electricity requires an adequate control scheme to maximise the generated power and enhance the system efficiency. Besides, more than half of solar irradiation on conventional PV panels is lost. The PV/T modules have been introduced to convert the lost irradiation to heat. Thus, a systematic review of system components, development, and strategies for grid-connected solar Photovoltaics (PVs) plants is presented. Two solar PVs, traditional PV and thermal (PV/T), are evaluated. Each grid-tied PV component is considered a subsystem to analyse the potential improvement of grid-connected PVs. This is from solar resources to grid-tied PV inverter techniques. An intensive assessment of the system improvements is presented to evaluate PV plants’ benefits, challenges, and potential solutions. The improvement trends for the novel generation of grid-connected PV systems consist of applying innovative approaches. It is also found that intelligent strategies optimally ensure the overall efficiency of grid-tied PVs using real-time control and measurement under innovative applications and technologies. These methods effectively assist in enhancing grid-tied diverse solar power approaches. Therefore, this paper would offer a significant foundation for advanced research into the subject of grid-tied PV and PV/T and their innovation and/or technology development.
