Heat sinks with different geometry designs have been proposed here to reinforce the heat dissipation rate from a concentrated photovoltaic cell to enhance the cell performance.
The photovoltaic was equipped with a heat sink made of plexiglass with 10mm wall thickness and 30mm height, which was filled by pure Polyethylene Glycol 1500 (PEG1500) as the PCM. To minimize the heat transfer rate from the side walls of the heat sink, a cover of polyurethane with low thermal conductivity surrounded the heat sink.
While the concentrated photovoltaic cells with the proposed Trapeze 1 heat sink with two triangle fins and simultaneously, the concentrated photovoltaic with the foamed rectangular heat sink possess the second rank in electricity generation with about 2.75 kWh and also improve the CO 2 emission reduction by about 10.7%.
Moreover, Subarna Maiti et al. studied the performance of cooling the concentrated photovoltaic panel by using a suitable liquid for the heat exchanger, using a square parabolic-type reflector. The results showed that a more than two-fold increase in output power was realized on a clear sunny day employing a 0.13 m 2 silicon solar module.
Therefore, although the both simulations and experiments indicate that the application of a heat sink to a solar module reduces the temperature, it does not give an accurate indication as to what the temperature reduction will be when the solar module and heat sink combination are inclined, as if mounted on a roof.
