Design and validation of MEMS based micro energy harvesting and thermal energy storage device

An abundant source of energy is available in solar radiation which could be used for the generation of electrical energy. This research paper investigates a new method for the conversion of solar thermal energy into electrical energy. This method uses the Thermoelectric Generator (TEG) coordinated with the Phase Change Material (PCM). To enhance the performance of solar TEG, Solar radiation is focused on the Fresnel lens and solar concentrator. The output obtained from the solar concentrator is more than from the Fresnel lens. From the concentrator, 1.38 Vis generated with a hot side TEG temperature of 195 degrees C and a cold side temperature of 62 degrees C in the day time and the off radiation maximum potential of 134 mv. The proposed system can harvest a maximum voltage of about 1.38 volts and 0.17 Watts of power during day time.
