Abstract :-Today’s world is trying to find more efficient energy storage systems for unconventional energy sources like wind energy, solar energy, etc. Porous materials which pursue increment in surface area also one of the solutions for the storage of energy received from unconventional energy sources. In solar parabolic trough collector, hollow pipe of aluminum or copper material is used as absorber which is generally used to receive the reflected rays of sun. The pipe is covered with evacuated tubes for the better absorption as well as to reduce convection. The heat is then transfer to liquid passing through that for the increase in temperature. In place of the hollow pipe absorber, porous material can be utilized which increases the heat transfer rate due to increment in surface area as well as decrement in velocity. In this review article, literature has been discussed for such absorber made of copper or aluminum metal foam which increases the efficiency of the solar parabolic trough collector.
