Parabolic trough solar collector is a solar thermal collector which works on solar energy, the efficiency of this collector depends on the thermal energy of sun. The main objective of this work to present an upto date literature review on the parabolic trough solar collector. During the literature survey from the various research paper related to parabolic trough solar collector it has been observed that there is a lot of research work have been done in the same field and still there is a large scope to work on the parabolic trough solar collector. From the literature review it has been also observed that many authors worked on numerical as well as experimental setups, many of them use various optimization technique which was validate by various simulation tools like ANSYS, computational fluids dynamics tool Fluent and many more.

The nonfragile cavity receiver is of high significance to the solar parabolic trough collector (PTC). In the present study, light distributions in the cavity under different tracking error angles and PTC configurations are analyzed. A new elliptical cavity geometry is proposed and analyzed. It is obtained from this study that light distribution on the tube receiver is asymmetrical when tracking error occurs. On increasing the tracking error angle, more lights are sheltered by the cavity outer surface. The PTC focal distance has negative correlation with the cavity open length, whereas the PTC concentration ratio has positive correlation with the cavity open length. Increasing the tracking error angle and increasing the PTC focal distance would both decrease the cavity blackness. Introducing a flat plate reflector at the elliptical cavity open inlet can largely increase the cavity darkness.
