Abstract- Reducing cell temperature is very important to improve cell efficiency and increase electrical output. This study indicates the need to reduce losses in the process of cooling the PV cell by controlling the air flow rate where the highest electrical efficiency of the cell at the airflow rate (0.049 kg/s). The results showed that the rate of reduction of the temperature of the cell reached (37.22%), and the temperature of the cell decreased by (22.2782 °C) as a result of cooling using air guides. The heat generated by the cooling process can be utilized in multiple applications as the difference between the inlet and outlet temperature of the air duct reached (13.717°C), and the increase in the thermal efficiency of the PV cell (68.7%).
