▎ 摘　　要

NOVELTY - Energy harvesting system (100) includes a solar cell (110) for generating electrical energy based on sunlight, an interface layer (120) located under the solar cell and comprising a heat transfer layer for transferring heat generated by the solar cell, and a thermoelectric device located under the interface layer, comprising a first electrode, a second electrode, and a thermoelectric channel located between the first and second electrodes, and configured to generate electrical energy based on a temperature difference between the first and second electrodes that occurs when heat generated by the solar cell is transferred to the first electrode through the heat transfer layer. A cooling layer located under the thermoelectric device and cooling the second electrode to increase the temperature difference. USE - Energy harvesting system. ADVANTAGE - The energy harvesting system has improved energy generation efficiency by effectively transferring heat generated in a solar cell and heat induced by light passing through the solar cell to the upper portion of a thermoelectric device by including an interface layer between the solar cell and the thermoelectric device and by cooling the lower portion of the thermoelectric device without additional power consumption by including a cooling layer under the thermoelectric device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a energy harvesting system using a solar cell and a thermoelectric device. 100Energy harvesting system 110Solar cell 120Interface layer 130Thermoelectric device 140Cooling layer
