<p>The hot weather caused an increase in temperature of the photovoltaic (PV) cells which drastically cut down the electricity produced by the PV module. The main determining factors of the heat exchange processes within the PV module and between the PV module and the outside environment are the primary thermal and optical characteristics, the type of material used, and its architectural design. To improve the heat transfer of the PV module, the temperature of the PV module was monitored while changing different environmental parameters in steady state, and physical parameters related to the PV module in transient state. The results obtained demonstrated the influence of thermo-physical parameters on the thermal performance of solar cells. In addition, the back layer of the PV module was examined, and it was found that the aluminum back layer was very effective in facilitating heat exchange with the environment thereby reducing the temperature of the PV module. Finally, two novel configurations were proposed as pipes running along the backside of the PV module. A temperature drop of as much as 12°C has been recorded for an incoming air temperature of 20°C and an airspeed of 2m/s.</p>
