Nonconventional energy sources like natural gas, coal, fossil fuels and petroleum are using extensively, leads to clean energy / renewable energy importance. Power generation with burning of fossil fuels can be changed using solar energy input source. Solar radiation incident on Photo voltaic Thermal (PVT) panel raises its temperaturę which tends to decrease the electrical output. Heat enhancement in Photo voltaic Thermal (PVT) panel can be reduced by attaching Phase Change Material (PCM) container on rear side of PV panel which increases the PVT efficiency. Novel technique and promising media for better thermal energy storage using PCM with fins, porous materials. Thermal conductivity of PCMs was low creates problem for energy storage and rate of retrieval. Improvement of thermal conductivity in PCMs and heat transfer enhancement can be done efficiently with the help of fins and porous materials of different designs. Present study provides optimum design of PCM container depth, fin height along with length of fin. Enhancement of heat transfer in Photo voltaic Thermal- Phase Change Material (PVT-PCM) will done by addition of Nano particles (Tio2, Sio2 and Al etc.)of high thermal conductivity along with PCM. Porous materials / fins can be made with metallic based materials nickel, copper, aluminum and carbon materials like graphite. These porous materials gave good results and efficient in heat transfer / thermal conductivity enhancement by 50–600 times than the conventional one. This paper gives the recommendations and conclusions to discuss research gap in this area PCM heat transfer enhancement to reduce the PVT panel temperature.
