Solar thermal, photovoltaic, and radiative cooling are the three main methods to harvest solar radiation and universe coldness for building energy conservation and carbon-emission reduction. In this regard, the hybrid solar photovoltaic/thermal (PV/T) system is especially favored because of its compact structure and high energy efficiency.
The hybrid PV/T system provides 20 % more energy compared to independent PV and thermal systems In contrast to water-cooled photovoltaic thermal systems, the employment of PCM confers approximately 33 % greater heat storage capacity and a substantial improvement in cooling performance spanning 75 %–100 %.
Solar energy is an important resource regarding the need for sustainable production of power around the world. Concentrated photovoltaic/thermal (CPV/T) hybrid technology is amongst the most promising systems due to its ability to harvest both electricity and thermal energy simultaneously.

These devices can be integrated into PV systems for power generation enhancement and PV thermal management [5]. The hybrid system, combining the PV and TEG systems, can produce more electricity by simultaneously utilizing the waste heat from the PV system through TEG. These hybrid systems are recently explored as a promising option.
At the same time, combining solar energy systems is a trend these days which aims to optimize the benefits from solar radiations. Photovoltaic/Thermal (PVT) hybrid solar system is obtained by combining solar thermal collectors and solar photovoltaics to enable a simultaneous generation of electricity and production of heat.
