Efficiency improvement of the photovoltaic energy conversion by application of the fins: An overview

One of the main issues related to the commercial available siliceous based photovoltaic technologies is efficiency degradation due to elevated operating temperatures. Improvement of the photovoltaic (PV) energy conversion can be obtained with application of the passive or active cooling techniques. This paper contains and overview and current status of the efficiency improvement in the case of the passive cooled PV panels. Considered passive cooling technique assumes aluminium fins that are positioned on the back side surface of the PV panel and that can enhance heat transfer from the backside surface to surroundings. Through this research it was concluded that passive cooling, using the aluminium fins, can ensure increase in the PV panel performance, as well as reasonable decrease of the PV panel operating temperature. Basically, an average difference in the electrical efficiency between the passive cooled and non-called PV panel is about 2%. In any case a fins based passive cooling has better performance then stand-alone PV panel, but further improvement of the proposed cooling techniques is needed to become more effective as well as more economically viable.
