Design, Fabrication, and Testing of Thermoelectric Generators Integrated on a Residential Window Frame

The paper contains the study on generating electrical energy using twelve thermoelectric generators placed inside an aluminum window frame. The harvesting circuit composed of twelve thermoelectric generators, a DC-DC boost converter, and a power bank. The hot side absorbs heat through rays of the sun between the period of 1:00 pm to 3:00 pm. The cold side is being cooled by the air of the fully air-conditioned room. The researchers measured the actual voltage to calculate the actual power, actual heat input, actual power, actual thermoelectric efficiency, and the time to fully charge a 7800mah power bank. The results show that the 2:00 pm mark records the highest temperature and highest voltage output.
