low cost. With this aim, in this investigation, the geometric and design parameters of a
parabolic trough solar collector (PTSC) have been examined and optimized with the dual
goal of maximizing efficiency and minimizing the levelized cost of heat energy (LCHE). It is
revealed that shuffling the types of design parameters like heat transfer fluid (HTF), absorber
material, and solar selective absorber coating (SSAC) has a considerable impact on thermal …
