Assessment of thermal performance of PV/T collectors under different enhancement methods: A review study

Population expansion & economic development in the majority of the world's countries have raised global energy dem&. According to international energy agencies, developing countries' energy consumption is increasing faster than in industrialized countries, & they would need nearly twice their existing capacity to meet energy dem& by 2020. It is also predicted that global energy consumption will rise by 44 % between 2006 & 2030. As a result, alternative energy sources must be defined in order to meet our energy needs while conserving conventional petroleum-based fuels. Solar energy is a clean energy source. Renewable systems have the potential to fulfill a large amount of the world's energy consumption. It has stabilized the hurtful impact of carbon emmissions of enhanced world energy consumption, including the reduction of major fossils fuels in the field of clean technology. The PVT system generates At the same time, electrical & thermal power are produced. The goal of this hybrid system was to use a cooling PV panel to improve electricity efficiency while also utilizing thermal energy for heating. The majority of PVT system research has been on heat transfer through an air or water-based medium. Nanofluids & phase-change materials have been combined with working fluid in recent years to improve PVT thermal performance while also introducing certain design parameters.
