We constructed a cooling system for solar cells using convection phenomena and investigated its cooling performance. The cooling system didn’t need any driving power or water resources. The convection cooler manufactured with a right-triangle shape of an air duct was attached to the rear of the solar cell to confirm that cooling was performed using convection phenomena. When the ratio of duct width to attachment surface width was 3:7, and the ratio of entrance height and exit height of duct was 5:1, it showed the best cooling performance. Comparative experiments with solar cells without convection cooler showed that cooling effects from 16.5°C to 20.9°C occurred after 40 minutes exposed to the 1300W Xenon lamp condition.
