Cold wind inlet Fig. 1 The structure of solar air conditioning / heating system The working principle of the system is that under normal working conditions of the solar cell, the heat of battery panel is taken away by the flow of the working fluid, which is water and water vapor, in the gravity heat pipe that is made of copper materials [4, 5] .
Accordingly, a mixture of Ag/CoSO4 nanoparticles was dispersed into the base fluid of propylene glycol as an optical SBS, and the heat pipe was joined to the back layer of the solar cell. SBS and heat pipe devices were used as the first and second thermal absorbers, respectively.
The PV module was introduced as a component of the thermal collector, and a thermal absorber plate was used to harvest waste heat from the rear of the PV panel [ 7 ]. By driving the working fluid, the generated heat can be removed in time; thus, the temperature of the solar cell can be controlled within an acceptable range.
Soliman et al. [ 80] reported on the use of flat heat pipes for solar cell thermal management. At a solar radiation energy of 3000 W/m 2, the acquired results suggest that the power production may be increased by 9.1% under the heat pipe cooled condition compared to the uncooled mode. Fig. 12.
A thermal absorber integrated with a heat pipe was placed underneath the solar cell to extract the waste heat. Running water was utilised to remove the unnecessary heat in the cooling chamber to produce hot water, as depicted in Fig. 17 c.
