The deposition of dust on the solar cell surface causes an obvious degradation in its performance efficiency, and as the cell is always exposed to outdoor conditions the dust always accumulates on it. The recent study aimed to investigate the photovoltaic cells pollution with dust. As dust consists of several components, the formation of the deposit dust on solar cells located Baghdad (Capital of Iraq) on the roof of the Energy and Renewable Energies Technology Center in The University of Technology campus was tested. Experimental tests were conducted to measure the current, voltage, power, and efficiency of the PV cells. The study results declared that there is a relation between the clean and polluted cells, and this relation is linear. This relation attaches the effect of dust with current, voltage, power, and efficiency. The study used an equation connect between the variables of the clean and polluted cells and defined the factor k for Baghdad city. The factor k value for the used cells is 0.00113.
