Dependence the photovoltaic panel efficiency on its temperature during operation takes lots of concern for both developers and users. The passive thermal control for photovoltaic cells has been discussed from formal researches. Using phase change materials(PCMs)for thermal energy storage (TES) systems gained attention from engineers. Therefore, the current work experimentally studies the performance of PV cells using various types of PCMs (RT28HC, RT35HC and RT44HC).These PCMs are considered as thermal conductivity enhancer (TCE) for the surface of heated plate made from aluminum to simulate the PV solar cell. The results demonstrate that the highest reduction in the front surface temperature (FST) are 52.3%, 54.2% and 57.7% which occurred with the third configuration, heat flux of 820 W/m2 and AL2O3 nanoparticles concentration of 0.77% for PCMs types RT35HC, RT28HC, and RT44HC, respectively at T∞=20 ±1°C.
