Abstract

We evaluate the storage performance of an integrated energy harvesting and storage system using a thermoelectric generator (TEG) and an organic energy storage device. The power generated by the TEG is obtained by varying the temperature of the heat source on the bottom surface of the TEG while keeping the opposite surface at a constant cooling temperature. The difference in temperature gradient (BT) increases the power generated by the TEG. Capacitance-voltage measurements were performed on the organic storage device to evaluate the storage capabilities of the embedded storage elements, CdS nanoparticles. The objective is to assess the possibility of the integrated system and evaluate the effectiveness of the storage device. Voltage, current and power density values are determined and compared for different load resistance. The results revealed that for the 100 K load resistor, the voltage across the capacitor was the maximum at a lower temperature gradient with a charge density of 5.14
