Parabolic trough solar collectors (PTSCs) or parabolic trough collectors have caught the interest of scientists and renewable energy enthusiasts due to their wide range of operating temperatures between 100 and 700 °C and their potential for power production as well as industrial process heating.
Same development level of oil and molten salt as HTFs in the parabolic trough solar collector is assumed, and the specific cost of the solar field with molten salt as a HTF is considered to be 190 €/m 2 which refers to the DSG technology.

But, liquid metals have yet to be used in a commercial parabolic trough power plant, despite their promising properties such as low viscosity, efficient heat transfer properties, and a broad working temperature range (98–883 °C), which have attracted researchers' interest to the use of liquid metals in solar thermal engineering .
In order to evaluate the thermodynamic and economic performances of the proposed OIL–MS system, the conventional solar thermal power systems equipped with parabolic trough solar collectors are selected as the reference systems, in which the oil and molten salt are used as HTF stand-only, and named OIL system and MS system, respectively.
