Abstract

This paper deals with the surface impurities that occur onto operating solar cells, a widespread problem. The depositions on the photovoltaic cells, represented by dust and dirt which appear inevitably, lead to deterioration over time or to the decrease of efficiency of the panels that contain the affected cells, and as a result there are losses that appear in the system. Some local depositions create shady areas, causing significant overheating which is experimentally highlighted.
