Transient thermal analyse of mini heat sink PV cells cooling for hot climate

The mono-crystalline photovoltaic cells are very sensitive to the ambient temperature despite the high conversion efficiency compared to other low-temperature solar cells. To enhance its efficiency we analyse of the Photovoltaic cells under conjugate heat and mass transfer for the active cooling within hot areas climates integration. The major objective of this study was to predict within 2D simulation the heat transfer behaviour of the materials then to optimize the geometry of heat exchanger depending on specified control parameters. Results show that the performance of using mini-channels heat sinks is significant in matter of thermal dissipation and low pressure drops, and the PV efficiency should increase for 8 % relatively to the standard efficiency, but in appropriate design and limitations.
