Electric energy plays a critical role in modern societies, supporting applications that range from residential use to industrial operations and advanced technological systems [1]. Rising global energy demand and increasing environmental concerns make the development of sustainable production technologies essential, and photovoltaic (PV) systems have become one of the most prominent renewable energy solutions [2, 3]. The performance of PV panels, which convert solar radiation directly into electricity, is highly sensitive to operating temperature [4, 5]. As the cell temperature increases, the electrical resistance of semiconductor materials rises, leading to efficiency losses and accelerated material degradation. This situation negatively affects the electrical output of the panel. To address these thermal challenges, a wide variety of cooling strategies have been proposed in the literature. Passive techniques such as heat sinks and phase change materials are commonly used, while active cooling methods that rely on forced air or liquid flow have also been widely implemented [6]. Among the active methods, thermoelectric cooling (TEC) attracts attention because it operates in a solid state, contains no moving components, has a compact structure, and is capable of providing both cooling and electricity generation through the Seebeck effect. When an electrical current is supplied, TEC modules create a temperature difference between their two sides, allowing heat on the PV panel surface to be transferred to the surroundings [7]. Experimental studies have shown that integrating thermoelectric cooling structures into PV panels can reduce operating temperature, thereby improving power output and the overall stability of the system. Building on these findings, the present study examines the performance of a hybrid cooling approach in which thermoelectric modules are combined with finned heat sinks and forced airflow applied at two different air flow rates. The effects of this finned TEC structure and its airflow supported heat dissipation on power reduction in a PV panel were evaluated through experimental tests conducted over an eighteen minute period.
