Abstract: With the advancement of civilization and hence the energy consumption, the need for exploring novel energy sources is also on the rise. Solar power generation is one of the fastest developing en-ergy sectors in the world. The conversion efficiency of a solar cell decreases with increase in the temperature of the junctions. Our research study focuses to reduce the junction heat by incorpora-tion of Loop Heat Pipes with Plate type Evaporator (WLHP-PE) to transport the heat generated from the panel to the ambient. The study showed that the temperature of the panel is reduced by 5 to 9 ºC. A rolled bond evaporator plate is attached to the bottom of the panel which acts as evapora-tor part of Loop Heat Pipe (WLHP-PE). Acetone, which is the working medium, filled in the WLHP-PE in liquid state to the required level to absorb the heat generated at the bottom of the pan-el and becomes vapour. This vapour transports the heat to the condenser section of the loop heat pipe, which is immersed in water bath. There the heat it is rejected to the water due to which the working medium is again converted to liquid state. For the given operating conditions, the conver-sion efficiency of PV module is increased by 10 to 12 % without any external power supply.
